I have a 1959 AC Model D grader and a at least 1965. The 1965 engine is frozen but everything else looks very good. The 1959 runs and everything works but is getting worn out. Has anyone pulled off the transmission-rear end and tandems in one piece and swapped them to another grader? Looks like it would be fairly simple to unbolt it from the frame and then lift off the frame and replace it with the newer frame.
