I've tried 4 different crossmembers for my swap now and not one of them has worked.. bah!
Here's a picture of two different styles of crossmembers - I need the one on the left, that has a fairly large bend in it. I believe these can be found on late 80's 5spd trucks.
This is the last piece of the puzzle on my 3.4l swap!
Let me know if anyone has one.
