T56 Install - Factory Crossmember Modification
 

I've read a few places that I could use the factory cross-member in my 1969 firebird for my LS2/T56 install. I've heard that some people have installed it upside down and used a ~2" spacer to retrofit to the T56.

Does anyone have any details on their install or details of the spacer block using this method? I'd like to have the cross-member ready for when I get ready to stab the engine/tranny in. Thanks.

How would installing it upside down work? The exhaust humps would be facing the wrong way.

We used a stock one before. We just cut a little off the ends, welded tabs to the subframe, and bolted it to those tabs.

The crossmember doesn't get turned upside down, just the trans mount tab...many cut it off, flip it over and reweld it so the trans sits lower....
