Uhh, CUCV bumpers will fit 81-87/91 trucks easily, as they *are* 81+ bumpers, just with extra holes.
They will NOT so easily fit onto 73-80's, especially in the front, as the frame horns are different. It won't be a bolt-up.
As merace says, they're nothing special. You would be better off cutting holes in your existing bumpers for the shackles if you can score those separately. I actually bent the bumper *on* my CUCV by a small fencepost impact :whistling: ... grrr.
