So, finally have a bunch of the pieces to the puzzle! Heres the list Guys!
1976 triumph spitfire
Isis power management
Bmw m42b18
stock diff with quaife (need to find)
Mazda rx7 front brakes
custom rear brakes
hubs into 4x100
Frame reinforcement w/ slightly hidden cage
i think the motor would be kinda fun in the car, but there is no turning back now....
Any ideas on a place to pick up a quaife unit?
