I think this kit already moves the wheel out from the center point of the kingpin. Adding spacers will bring even farther out. Just remember the farther you move the tire from the kingpin/ turning point the less leverage you have in steering. This would mean harder steering in my opinion. If you have power steering its not much of a problem, just hard on the wheel bearings I would think.

thats for certain, thats why i bought aftermarket truck mag rims from jegs. they bell outward enough that i dont have to worry about clearance issues with the caliper plus they are super cheap.

Front Disc brake conversion
1. Crack front wheel nuts loose, chock up rear wheels. Jack up front end of car, support outer
control arms with jackstands. Remove front wheels, drum/hub assembly. Put a few drops of
penetrant oil, such as AeroKroil on brakeline nuts where they screw into rubber lines.
2. Take drum/hub assembly and remove drum by using a swedge cutter on the base of the studs,
then pressing out and discarding studs. Clean off wheel surface and register with wire wheel or
bead blaster. Machine outer edge of hub flange to fit inside rotor with about 0.010" loose fit. This
is important, as it is what centers the rotor on the hub. A 100 hubs will not require machining.
Replace studs with X" longer or more studs. Mopar used several different suppliers for the
drums, and they had 3 different sized studs. Dorman 610-103 is one. Best approach is to use an
ARP or Moser stud and cut down to length.
3. Disconnect brake flexible line at frame by unscrewing hardline nut with flare wrench, then
removing nut. Undo and remove drum retaining bolts. Remove drum backing plate, hose and all
drum hardware in one assembly. Clean off spindle assembly well.
4. Place adapter plate over spindle with caliper bolt retaining nut welds facing inward, and caliper
opening to the rear (A 100 faces forward). Make sure no dirt is lodged between spindle and plate.
There was some variance in the spindle's lower bolt holes, so we left the holes small. Drill out to
match spindle hole size.
5. Verify that rotor lays flat against hub by fitting rotor backwards onto hub. If the stud knurls
interfere with rotor, countersink stud holes in rotor to clear knurls.
6. Clean and repack wheel bearings. Install new seal. Assemble hub onto spindle, tighten outer nut
to spec, then secure with keeper, new cotter pin and dustcap.
7. Place rotor onto hub, and run two or three lugnuts down finger tight to retain rotor. Wipe down
rotor with alcohol, lacquer thinner or other cleaner.
8. Wash hands! Rotor must be squeaky clean.
9. Slide assembly into caliper bracket. We recommend buying loaded calipers. Tighten caliper bolts

use a disc proportioning valve if rears suffer from excessive lockup in panic stops.

eliminate most of the air, then pump bleed and test, otherwise your distribution block may jam

The Rotors I purchased ( 1995-97 Ford Crown Vic front ) did not require that I machine my hubs. There is a bunch of clearance so the hubs just drop in. I'm curious if any of you have seen this or if it's just the way my rotors are from the manufacturer or distributor I purchased my parts from.

Also, I found that the Scarebird plates (after slightly opening up the larger diameter bottom holes) were also slightly off in center to center location on the smaller diameter upper holes. That meat that I needed to drill them slightly larger to compensate for the centers being off, or machine them to the correct centerline distance.

mine do the same thing. as long as your hub fits with minimal gap/ wiggle room once you have the whole assembly bolted on and the rim on and tight its not an issue. never had a problem with my rotors slipping or shifting under even the most dramatic testing.

WWW.theramman.com has a complete bolt on kit using all Chrysler parts. Rotors and calibers are '76 New Yorker stuff IIRC. You can google a utube video which explains it.
One day I will own a Sweptline!

The stock rims ended up fitting fine once I ground off the edges on the calipers.

Beware of Scarebird's Quality Control. I found 4 issues to consider:

1) I ordered their new hubs which were machined to two different sizes. The wheel bearings fit fine, but the amount of metal on each side was different. I haven't detected any issue with this yet, but somehow I gotta think that each side spins with an uneven force.

2) This is the MAJOR RED FLAG: If I hadn't checked inside of the hubs, I'd probably have ground up the wheel bearings after a few months. The problem was that Scarebird failed to clean out the inside of the hubs. There was a lot of metal shavings & bits from the machining that somehow got left inside. There was approximately half a teaspoon of this metal debris. I can't help but think that Scarebird would've tried to pin any failure on me. Luckily I caught this.

3) In the Swap to Disc Brakes, Scarebird made no reference to which Master Cylinder to use. Nor did they even refer to the Metering Block (many seem to call this the Proportioning Valve - not the same). I am not the expert here, so I didn't replace my Metering Block at first. However, after much trouble getting pressure - then having the brakes lock such that after about 5 miles, the brakes were super hot & smoking. Because of this, I had to return my calipers (thankfully Advance Auto exchanged them at no cost). I finally figured this issue out & got Disc Brake combination Metering Block/Prop Valve (an SSBC unit. btw, this was abt $10 more than the basic brass Metering Blocks, but I think the value was worth the price).

Because I had to change the Metering Block, I had to cut & re-fit the brake lines due to different valve nut sizes. This was a real pain, as I had to re-flare my lines to take the correct size nuts. BTW, I took this as an opportunity to replace my old metal lines.

4) Location of Caliper: My calipers installed best if mounted to the rear of the wheel assembly. This is due to calipoers & anti-sway bar interference. I have seen several opinions about mounting the calipers forward, or rearward (mine). I have never seen a definitive case for either side being correct. FWIW, I have mounted calipers to the rear on 2 Barracudas & never had any issues with drivability/handling, safety, etc. The fact that Scarebird did not bother to address this issue (esp the caliper/anti-sway bar interference) tells me that Scarebird doesn't go the distance to know it's product like they should. They should have figured these things out - not just left the 'user in the field' to figure out how to deal with their shortcomings.

I would definitely upgrade to disc brakes on my D100 again. However, I would check out the competition (I think 'AAJ' is one).

With all the trouble that I had to figure out on my own, plus the potentially disastrous failure that was thankfully averted, I would rate Scarebird a 2.0 out of a 5.0.

From the factory the sweptline trucks didn't have a metering block/proportioning valve. They only had a switch that would cause the brake light on the dash to light when the brake pressure was low. I believe the need for a metering block/proportioning valve has been covered in nearly every thread on converting to disc brakes.

They don't know these trucks like some of us do. The truck they used for mocking up this set up was a pre 70 truck and didn't have the sway bar or any provision for it.

The Switch goes into the brass block (which, in my terminology, is the metering block...maybe somebody has a different
name for it). ANyway, the stock setup had more than just a switch. It's definitely not a prop valve. ANyway, send me a link to the threads that you say cover all that - I'm always wanting to add to my 'Lessons Learnt'.

Other than buying Scarebird hubs, which hubs do I use? Are there any hubs from other makes/models that will work? With no modifications? I have a 1970 D 100

I believe you have to have your hubs separated from your drum and use them.

Hi everyone. With my first post I'll mention a thing or two I've seen in the middle of my scarebird conversion. First, make sure and figure out the stud you need before you buy new ones. I bought 40 bucks worth of ARPs and they were wrong knurl size. And can't find ARPs for .650" knurl. So Im getting some Dorman and hope they're long enough. And I'm guilty of putting my plates on backwards at first because I thought my 65 was considered early in the instructions. Got that figured out. Mine also ended up with lots of clearance around hub using crown Vic rotor. And I sure had to get the torch out and heat the lower front bolt on the driver's side. That's all for now....will inform about the studs I end up using.
