I’m trying to build a couple “Close Ratio” transmissions for Triumph Spitfire Vintage Racers. The easiest way I’ve found to achieve this is to modify a Triumph GT6 transmission. There are “early” and “late” models of this box. The late ones are preferred (stronger main shaft and synchros) and will have a “KE” or “KF” prefix on the ID number. This number can be found on the top of the transmission case, revealed by a notch in the top cover that the shifter mechanism uses for a mount.
For an image of where this ID number is located, please see The Triumph Experience web site forum accessed by this link –
Joe, Someone on Denver Craigslist has 2 for sale. $600.00
Fyi, I have an extra gt6 Bellhousing if you want it.
Thanks, Bob! I’ve emailed the seller. We’ll see if these are the right ones.
No need for Gt6 Bell Housings. These would be modified for Spitfires. Now, if you have any of the aluminum Spitfire / Herald bell housings I’d be interested! I have several of the cast iron model, but only one of the aluminum.
