I just got out the old original 3 speed tranny and I am doing a 5 speed on the floor (yeah I know I ordered the new starter and still deciding on different seats) but I am doing the swap at school and can not use the original cross member. Instead, my shop instructor said I would need a channel. Is it basically a channel and where could I get this? He says Ace hardware, home depot, and acouple of other local places but I am just not all too sure on what to get.

Help appriciated.
