Cab swap question

[66patrick]

What, exactly, keeps one from putting a '69-'71 cab on an earlier chassis???

as long as you do the whole cab, doors and all, nothing keeps you from doing it.

Somewhere on here, long ago, I remember one guy had a later ('70) cab for sale, back when I was considering putting the '67 D200 on the road instead of parting it. I'd mentioned doing a cab swap, and they answered "oh, no, a '69-'71 cab won't work on an earlier frame" and they never elaborated as to why, other than something about cab mounts! So that's why I'm asking. So, there is one saying "yes, it matters" and one saying "no, it doesn't".

as far as i understand it, the cab swap runs into problems trying to use the early doors and dash in a late cab. i have never heard anything about the cab mounts being different. on my 66 i used a set of cab rubbers from a 70 modle i pulled from the local junk yard. looked to me like all the lounts were the same, the rubber cab mounts swapped without issue.

I thought that there was something with the steering column that you had to modify?

[66patrick]

I know that the dash metal does not swap between the late and the early cabs without a lot of work, and the thing with the doors (fridge vs. button handles) I have known about that, too. It would seem that if one had a D-200 chassis from 1965.2-1968 and wanted to put a '71 body on it, it should work without a problem, as you said. Just curious now, for future project possiblities!

The question is pretty much moot for me now, anyway, since I've pretty much got the '67 down to the point of hauling it off. For anyone needing a rolling '67 D-200 chassis, here's your chance before it goes to the scrap - You get a complete, rolling chassis, a cab-only, and the truck's title and door tag for $150. It's going way by the end of March, so don't fart around if you are needing 3/4-ton stuff, especially a 4.10 Dana, good brake drums, E-brake cables (they function well!), and so forth!

for manual trucks the early stuff uses hydraulics and the later stuff is mechanical. other than what trey brought up i am not sure what other hold-ups there would be...

Ben, that's it! It was the hydraulic vs. mechanical linkages for the clutch between the '68-earlier trucks and the later ones! I knew someone would know. I couldn't remember what the ^&*^ it was that kept me from doing that very swap, and that was it! Thanks!

What about overall length? I though the early models were a bit shorter beds???

The cab is the same length though.

61 to 66 direct swap with only miner changes in
the wing window mounting.
67 to 68 direct swap with no issues
69 to 71 direct swap with no issues

Dash parts 61 to 68 with only miner changes
in things like item placement. Gauge clusters
all swap, but two main types if you want to
stay stock on gauges 61 to 64-- 65 to 68 (not counting
round HD sets with or without tack 61 to 68)

Dash 69 to 71 changed the way it is mounted
from earlier cabs and sheet metal also changed
on the dash> many up dates. Cowl cover change
to use new wiper system> side to side action instead
of center out. Also steering column changed the way
it is mounted to the floor from earlier years and
clutch peddle changed to use linkage.


Doors 61 to 66 no changes other than wing window
mounting. Pull fridge handle.

Doors 67 to 71- pushbutton handle--
change in 68> window crank, inside release handle and fiber glass panel/arm rest.
NO outside changes> 68 to 71 will direct swap,
(67 will also swap- but inside there like early doors, one year thing**)
>> striker and lock change in 67 from earlier
types, this also effects the sriker mount on the
door post and how the sheet metal is shaped
from the earlier trucks.

** you will find some 67's with early doors
(fridge handles), so not
all will swap to the later cabs with out mods.
