Dremel + eye balls + cardboard template + couple hours work = success.

This is bread & butter basics of modification, all you're doing is removing a little metal from the chassis until the new tranny fits, then make a mount for the side of the tranny that needs it so it can bolt in place- as per the pics.

If you cant figure out something so straight forward, maybe you might want to reconcider your options. A spare chassis costs about $10 on ebay should you feel the need to practice...
