There might be some minor differences in front bumper mount holes. If you remove the plates that were added to the rear of the 74 frame you will have a frame that can be used for a 69-73 car.

Make sure the frame is indeed a 74. If it is a later year you will have to modify the rear portion of the frame extensively to fit a chrome bumper car.

Frame Changes 63-82

Body mounts changed in '73.

I had read somewhere that the body mounts on the frame were lowered 1/2" to allow for the 73's rubber body mounts. After looking at the drawings in the AIM's it appears that the mounts were lowered 1/8" or less, not enough to worry about. When the rubber bshings are torqued down they are probably about the same thickness as the solid bushings anyway.
