What gear box will fit

[Sid_taylor]

The nova Iam running I believe has an f13 gearbox with a 4.1 diff .if I wanted something more suited for mixed driving not just balls out back road driving . What would box could I use ?

Try an F13 with a lower final drive for better cruising. e.g. 3.7 FD

[Sid_taylor]

Is the f13 box supposed to be 4 speed

[Iain]

I thought all F13 were 5spd
