I am watching this because I have sort of the same issue. I have the T-56 magnum and want to keep the stock console. The stock Tremec shifter has two really nice boots on it and they don't leak. Problem is the shifter handle attaches on the side and hits the console insert in the 1-2 gate and also going into reverse on the other side.
I would consider one of the shorter designs, but I have read threads where people have leaking issues and that isn't something I want to mess with. Who has found a good solution to this ? I know it is probably easy but I haven't figured it out yet.
Here is the thread on leaking shifters. I am not sure if this was ever resolved ?
