Is there any frame differences from a 1974 to a 1976 frame?

[dhdescender]

My 1976 blazer tub is currently sitting on a '78 frame, and one of the body mounts doesn't line up, becase the floor changed in '78. I'm after the crossmember that is just behind the doors and supports the floor.

I've found a 74 that a guy is parting out, since the floors are the same, and same generation blazer, can I assume that this crossmember should be in there?

Thanks.

no major changes, but i do remember one specific change.
the very front cross member where the brake distribution block bolts to is SLIGHTLY different. this should not affect your body swap at all.
there was another couple differenceas but i cant not remember them off the top of my head at the moment. like i said, they are tiny things.
