I only bolted the bracket to the bell housing. Actually the first trans I used had side shifting rods so I had to trim away that side, it's been fine for over 20 years. If there is room on side of T-5 you might be able to fab a bracket. I made a simple bracket to attach the park brake handle to the passenger side of the T-5, fit perfect through the original hole in the floor.

Also if you can send me your email I can send some pics.

It's easier to get forgiveness than permission!
