Hey how hard is it to convert a 81 4spd 3b 60series cruiser to a 5spd? Will a 5spd bolt up from a 4litre six cylinder 60 cruiser? cheers

yep and i have 1 heading my way in a week or two if you are keen

H series diesels share the same input shaft as F series petrols ie 10 spline short shaft.B series diesels are 21 spline long shaft. 5 Speed 60 series boxes are basically a 4 speed with 5th gear in a housing between the gearbox and transfer.You will need to alter your driveshaft lengths but otherwise not much else .Hope this helps cheers sig

So will have to use a 5spd from the b series then? Are they the same gearbox in the 70series with 3b in them? How much you looking for gearbox mudluva? cheers
