Well i got it fitted today using my bell housing and keeping the overdrive unit attached to its original gearbox. I will finish it tomorrow, fill it with fresh oil, fit a breather and go for a quick road test. Fingers crossed eh
One problem that i have already found is that the speedo cable for an o/d must have had another type of fitting because mine will not connect. Anyone know if they are avaliable new or where to find them?
I will post some pictures when i get a chance. It took me six hours in total today and was an easy job with no problems at all. Only bit that required some thought was the rear mount having different fixings. I removed the 1/2" studs from the mount and used bolts into the ally O/D housing. Other than that it was an absolute joy to work on.

most pleasant gearbox change i ever did
