Hi Norm,

Yes jeff's webpage as a lot of stuff in it!
The torque converter will give the best performance and last the longest.

Best of luck with the frame and gokart, and also the bushing for the 
torque converter.
Take some photos of the kart build and steps you take, and feel free to 
email some onto me here - I would be very interested in seeing the 
development and building of a kart. It has been quite a while since I was 
building karts, and I didnt take enough photos!

Best of Luck,
