T56 crossmember same for LT1 and LS1?
I browsed BMR website and I notice they only sell one crossmember for T56. Is the crossmember independent of engine type, or do I need a specific design for LS swap?
Same question goes for their TH400 crossmember with LS engine.
Thanks!

Thanks. Didn't know if there were changes to the back mounting location of the trans over the years.

This is what i had to do to mine with the straight up swap mounts and not using the 1 inch set back, so you can imagine, the 1 inch set back plates or other mount that positions everything in the correct location, the original holes would probably work perfect:
