Well I am going to start the motor swap this weekend....from my straight 6 200ci to my nice 302

...can't wait....already bought some shorty headers and underdrive pulleys for the 302....hope to add some more stuff to it after its in....got a question about the transmission. I'm taking the Tremec T5 tranny out of the 87 and putting it in my 65, is there a new cross memeber I'm going to have to buy? is it going to fit right in? and the same questions with the 8.8 rear end?! If any of you mustang guru's know...I would highly appreciate the help....thank you!!
Tom
