Another question.
The old frame had the crossmember brackets holding it in. The crossmember is rusted on the ends so is unusable. I was going to reuse the pocket brackets but the crossmember from the new frame has a raised section that won't slide into the brackets so it looks like I'll have to just bolt it to the frame. Should there be rubber insulators between the crossmember and frame?



Thank's in advance.

I believe Chevy used a tubular crossmember that bolted directly to the frame on each side with no rubber.
Buick, Olds and Pontiac A body cars used a stamped/shaped steel crossmember with tabs that fit into rubber "sandwiches". The sandwich was retained by a clamshell clamp thingy and two bolts on each side. I think the BOP cars did it this way to remove just a little more drivetrain vibrations since they were a bit more upscale from the chevys.

I'd say just use whatever works.
