Wait wait wait.

Isn't a 74 right side shift and 77 left side ?

Forgive me, I am an old man.

We can do anything but some things require more work than others.

The Marston Sporton runs a TT Industries 5 speed box and a Newby Clutch.

But that's probably a lot more money and time than you want to do.

gears and shafts are the same. shift tower is the same. shift cam axle is shorter - no problem. trap door has notch for '77 up shifter shaft, but not used on '76 and earlier - n/a.

It just depends on what you have to hand or what you might need to buy in. If I had no gearbox at all and had to buy the complete box I would just look for a --71 to -74 box. But having said that if someone offered me a -77 box at the right price I could use most of that.

It all depends on what you have in your hands at the time.
