Cab level?

[fireguyfire]

I’m just about to paint my 70 D100 back to the factory colour (Tor red with a white painted top) after doing a ton of metal repair on the cab including new floor pans and rockers (thanks exline!)

Since I replaced so much metal and the cab was so rotten, I’m hoping I got things back to dead factory spec, but won’t know for sure until I drop the cab back into the restored frame. The rear frame mount pouts are untouched so I know they are still factory correct.
My question is, with the cab remounted, should the floor where the seat sits, and the bottom of the inside of the rocker be parallel to the ground?
I’m thinking if I put the rear mounts back in, I can them shim the front mounts to make the cab level front to back and side to side before tightening down the front mounts.

Does this make sense?

Probably should be parallel to the frame. The ground is irrelevant as the angle would change with tires sizes and different weights/loads as well as spring sag over the yrs. IE, how would u know the change in springs w/o an engine, bed or front clip on it?

When I put the cab on my 66 and then installed box I had to readjust cab to line up with box. The original rubber idolaters had compressed a bit. Just had to use some very large washers to adjust.
