Thank you Dieselwrencher and I’ll keep that in mind. The yellow 54 belongs to one of the guys at The Garage Inc. pretty sweet project that looks cool with those fancy wheels!!
Once the rest of the K3500 cab is removed we can use the spare 69 cab and the 72 front clip to start mock up. This and starting repairs on the 72 cab pass thru should keep me plenty busy this winter.
Below are some GM frame dimensions to digest. First drawing is from the 67-72 AIM, a 2wd cab & chassis 133" frame. Next two are the newer 4wd cab & chassis crew cab 164.5" frame & cab. Last is a newer regular cab to get the front cab mount measurement.
Frame widths are almost identical (.06 difference) nice…
