try nanceybrown on here he has one of a 79,will fit yours asl ong as its the later one. ie not cast.he works of shore so if ya cant get hold of him send me a pm and il ring him.
I need an early one and although its a LHD, I actually just need the main shaft out of it, so a RHD one would be ok. Apparently they are the same. Anyone got either a LHD or RHD box for sale???
