Anyone done a 5 speed conversion on an early A?

The Tremec 5-speed install isn't that difficult, but it's more involved than simply cutting a hole in the tunnel and making a new hump. You'll need to completely remove the center of the tunnel and construct a new hoop over the torsion bar crossmember. I took a hybrid approach of severely hogging out the top of the Tremec box on a Bridgeport mill and then butchering and reinforcing the factory hoop (effectively making it a box tube) to obtain clearance and proper driveline angle.

That said, I can't think of a mod I've made that I've been happier with on my 65 Barracuda. I've attached a link to some pictures. Let me know if you have any specific questions.
