Guys,
I am an older guy who has an RT104 4 speed fitted behind a Holden 3.3ltr Red motor. It goes well, but I want a bit more economy.
I have been told that a 5th Gear extension housing can be fitted to the RT104 out of a Celica?
Any one know how to do this or where I can get the parts/whole gearbox.
Cheers
