Cross member for A-body
#2
The one I bought you can rotate the trans cross member into place if that makes sense with a slight modification. We had to trim the opposite corners to be able to do it but it works. Bought it from CPP.

The CPP part number is XMCH64677 for the 1964 to 1967 A bodies. Hope this helps. I am sure other companies sell them. I think the partnumber is XMCH68727 for the 1968 to 1972 A Bodies.
