The 69-72 stock frame is 1 inch longer than the 1965. Finding one is the problem. The 73-79 is 3 in he's with will need shorting. Was wondering if a 80 or 90 or 2000+ would work and what problems would encounter.

I have located a 65 crewcab that is frame less. Have been trying to find a 4 wheel drive frame.
From a 69-72 crew do to length of wheel base being closest.to the 65. Was wondering what else would work without a major fix.

Is this the same with crewcabs
