Roger, I've been gathering the parts to convert a 3 rail gearbox to OD for my '74 Spit. I was able to get the OD mainshaft ($230) from Spitbits, and the adapter plate ($115) from Rimmer without any problems. Both items are still listed as available from the respective suppliers. Rimmer also lists the rear mount and mounting plate, which are different than the non-OD version. There are a couple other parts that will be needed that I forgot earlier. You'll need a 90 degree speedo cable adapter and OD inhibitor switch and mounting bracket (keeps OD from engaging in 1st or 2nd gear.) Both are shown as available from Rimmer, but others may have them as well. As Barry pointed out, it is an involved conversion. And not cheap. But certainly doable. And cheaper than a Ford type 9 5 speed conversion kit.

The input shaft is different, as well as the bell housing, and as far as I know no late model single rail could be made to fit without extensive mods to the GT6 bell housing among other things. To fit a J type, which is what I did on my 70 GT6 you would need the adapter (which is kind of rare since it is only used on three rail Spits Heralds and Vitesse, the output or main shaft which is also pretty rare, Overdrive mount and bracket, and overdrive drive shaft (or you can shorten yours). You also need to cut the tunnel in the floor to clear the overdrive unit, and add the cover extension (or make your own) to cover the section that you just removed. Also, the wiring would also have to be added for the switch - not really a straight-forward conversion, but it can be done Barry Schwartz Original message ************************************* 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? -------------------------------------------------------------------- mail2web.com What can On Demand Business Solutions do for you? http://link.mail2web.com/Business/SharePoint _______________________________________________ [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]
