Errol,
Is the 71c gearbox the same ratios in the silvias and R31?What about the 720 4wd
with the z24,is that a 71c as a mate said he used a box out of one and he had to
modify the L series bell housing to suit the larger bearing.Can I use the dogleg
bell housing as it looks compatable as far as bolt pattern goes.What length is
the 71c and what what has to be done to the crossmember.Sorry about all the
questions but it seems like the way to go.
