Roger, As I recall, the Spitfire gearbox is not a bolt on to the GT6 engine. I believe the input shafts and bell housing are different. The cases are the same, so putting a J type OD on a GT6 3 rail box is possible. The GT6 never used a J type OD, but you can get the mainshaft and adapter plate you'd need. You'll need a shorter driveshaft, rear mounting plate, OD switch, and wiring to complete the transformation as well. Take a look at Paul Tegler's website. He's done the conversion, and I believe he has a page on it. www.teglerizer.com.
Hope this helps.

I have a 68 GT6 without an overdrive and would like to put one in if I ever get it rebuilt. I had a chance to buy a later Spitifire tranny with overdrive of unknown condition fairly cheap. I did not buy it as I was afraid it would be too much trouble to get it to work. Did I miss out on an opportunity? - Not counting the possibility of selling it for a profit. Also, I know of just an overdrive unit J type - supposedly good condition. I assume the parts to connect to my GT6 tranny would be impossible to find. Is that correct? Thanks, Roger Elliott 68 GT6 _______________________________________________ [email protected] Donate: http://www.team.net/donate.html Suggested annual donation $11.47 Archive: http://www.team.net/archive Forums: http://www.team.net/forums Unsubscribe/Manage: http://autox.team.net/mailman/options/spitfires/[email protected] _______________________________________________ [email protected] Donate: http://www.team.net/donate.html Suggested annual donation $11.47 Archive: http://www.team.net/archive Forums: http://www.team.net/forums Unsubscribe/Manage: http://autox.team.net/mailman/options/spitfires/[email protected]
