all 1 tons and 4x4's were leaf straight rail frames

leaf spring setup can be swapped onto any frame, coils can only be swapped onto 1/2 ton and 3/4 ton frames without fabrication.

leaf rear was optionally available on 1/2 and 3/4 ton 2wd chassies and the frames are all technically coil frames,
the frame width in front of and behind axle is same width on them all, roughly 34", so that leaves can be optionally installed if are ordered, the only real difference being that most coil holes are not drilled in leaf ordered frames and leaf ordered frames dont have locating ridges near the hanger brackets. its easy to spot and see once youve had a couple or more of each type of frame and also of 1 ton ones also.

38.5" roughly over axle on 1/2 and 3/4 ton 2wd frames

crossmember over axle does differ between leaf and coil, are swappable, no biggie. crossmember that trailing arm pivot brackets attach to lok same between leaf and coil, at least the ones i have out here do anyways, identical

good luck
