Small block to big block trans cross member doesn't work after swap?

Plus I just measured the circumference of the small block bell housing vs the big block bell housing and sure enough the big block is larger, which is what is causing the clearance issue with the small block 360 cross member.

I thought I had read multiple times that all the cross members were the same, measurement wise.

So now I need to know what guys are using to bolt a big block 727 in an A-body....?
