4 x 4 frames are also 2" deeper in the middle section
ron So does that mean a 62 cab will bolt onto a 63-66 frame without any modification to the mounts? no. mounting points on a 60-62 are wider. one just has to move the mounting points in the floor to accommodate the 63-66 frame mounts. but you can mount the later frt crossmembers in, up to 87 with a few modifications(fine width wise). the rad support is the only real thing that will directly mount across them all ron | | |
