The body mounts in the rear seat footwell area are inside the frame on '73 - '75 and outside on '76 and up.

So that the only difference? Body mounts?

The earlier frames are straighter between the front and rear axle humps, and the frame rails run parallel. The later frames have a dip to clear the rear seat footwell, and spread out in the middle.

I stuck a older tub on a newer frame . Front and rear monts line up . Middle are not the same . The sliders will tie in there in my case and hold the body on better

The changeover year is actually '78 not '76. 73-77 are the same and '78 up are the same. I have an early tub on a late frame and it was no fun having to fab up that center body mount...plus i have a weird gap where the footwell used to be.

Yup, my mistake on the year.
