As far as I am aware, they are the same less some differences on the front frame horns for the bumper differences. You can cut the older 73-80 frames to make the 81 - 87 trucks bumpers fit properly, and they otherwise line straight up.

Here is my 3/4 ton 4x4 frame from a 79 donor: First is a crappy shot in my garage (too dark for the camera) of the whole bare frame before I started on it, then a picture of the coated front, and finally another crappy shot from inside of the back (not yet complete, gonna take the leaf springs off, shoot them with graphite empregnated paint, and I gotta wirebrush a few places before I can put coating on them etc)
