Elevations between front and rear cab mount. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone have the difference in height between the front and rear cab mount for a 63-66 C10-C20 frame? I've looked in the shop manual, chassis builders, parts book, truck data book to no avail.

perhaps you just use shims to make sure that everything is in alignment. they may not have had a static measurement

The dimensions I do have are incomplete in this area. I'd like to build a jig for replacing the bottom end of the cab.

could you just build the jig off your frame?

I take it that this is the area which you are asking about. what are the figures there at the area of the rear mount. hard to define from your drawing

I was thinking someone might have those crash sheet specs, you know to straighten a frame. I think I could level out my frame and take an uneducated guess, but, I was hoping for something along the lines of a spec.

I have the book in front of me Ron, but it has no dimensions for the height of the frame brackets, just the location of the holes.

When I built my rear cab brackets, I believe the dimension was ~1.00 above the frame rail @ the bushing 'platform'. I used 1" tubing clamped to some angle steel to square, tack, & weld everything.

I got my dimensions off of a 65 swb frame that was tweaked too much (for my taste) to cut & modify.

I just went out to the garage and measured mine. I stuck a piece of EMT across the bottom of the frame. Measuring from the top of it, which would be the bottom (underneath part) of the frame, the front measures 3 3/4" to the top of the mount where the bushing goes and the rear is 7 1/8". Hope this helps some.

I thought 1bad62pro/street posted some crash sheets once, but I couldn't find them in the thread I thought... so they could be anywhere!

I went out and measured mine after leveling it off. Assuming the top of the frame is a level plane I measured and got 3 1/4", 1" from the top of the rear mount to the top of the frame - 2 1/4" down from the top of the frame to the top of the front mount. Which if you do the math, measurements provided by CSoliz, you end up with 3 3/8". Both within range. As padresag mention a little shimming required.
