No it is the corvette transmission we gave away the engine and transmission that was in the truck. Is there like a piece you can put on the transmission or do you have to buy a new piece to exchange on the tranny?

 

O.K., got it...(pics really help! )
I think you're SOL, as far as getting a crossmember from a parts house. [&o]
As I mentioned before, a good fab shop or a good welder can fab oneup for ya.They might evenbe able to use your original crossmember and do alterations.
If you have the crossmember that came with the Vette set up, one could combine the two, which is the route I would take, follow me here? I do stuff like that from time to time. Ain't no step for a stepper! It won't be hard, just have to do your measurements and get the alignment right.
Wish I had a quicker cure for ya.

I might be possible to make an adaptor to go from the tranny to the crossmember.
