Recommendations on Competition Spitfire Gearboxes Wanted

[EISANDIEGO@aol.com]

FOTers

    I would appreciate some insight into the direction one should go with 
competition Spitfire gearboxes. There has been past FOT discussions about 
substituting GT6 gear boxes as well as substituting TR7 gears (GT6 box?). 
There has also been some mention of substituting with other marques/sources.

    Thanks to all for their previous suggestions about seats. Decided to go 
with Kirby.
