Hi yvh,
I think it does matter.
The position of the frame extensions on the front of the frame rails is adjustable.
THAT adjustment determines how the core support sits on the front crossmember AND how the front bumper braces at both the ends, and the center brace are aligned.
Also, the 2 small brackets on the front crossmember should be off at this time because they should only be bolted into position after the front bumper and the bumper guards are satisfactorily aligned with the body.
You can't do any of that until the body os on the chassis. You'll still have the access you'll need to put the parts in place and adjust them.
Regards,
Alan

No , don't put the three pieces on yet. I just helped put a 72 body back on without the big crossmember , plenty of room to do it after the final alignment of body to frame

also depends on how it was shimmed before the body removal. if all is the same you should have the same bolt points and same amount of shims. a little off one way or the other will effect (affect?) your shims during your body adjustment. the shimming and body adjustment is your nightmare, not that frame plate. almost made me want to sell it all and buy a camaro...
