[Fot] Transmission for racing GT6+

[igofaster at charter.net]

Hello! I'm new to the forum, invited by Bob Kramer. I'm a longtime Triumph friend. I purchased this year the GT6 built by Bob Davis in central Florida. Way nice race preparred GT6, Bob Kramer can attest. My dilema is Mr. Davis did a heck of a job with the Toyota T5 gearbox conversion on the GT6. Recently with CVAR in Texas I enrolled in the driving school at TWS with the GT6. CVAR will allow me to continue for a short time to participate on a no points basis but I must return the Triumph to an appropriate gearbox. I'm open to suggestions. I've always felt the gearbox in the GT6's were soft at best. I had a TR6 gearbox I attempted to install at one time but looked like the frame would have to be cut and modified. I have a nice 1969 with an overdrive transmission, not sure if that is the answer. I only used 5th gear at TWS on the staightaway past the finish line and in the cooldown lap. The diff is the 3.73 (I think) locked. 
looking foward to the input...
kindest regards,
Bobby Whitehead
