r+d plated unit in my car, its yet to be driven in anger with the new diff and quaife box so i cant comment on performance but i trust every word that bernie ( www.gearboxman.co.uk ) tells me same said for marco both these chgaps have forgotten way more than i will ever know about cossie transmission

mine was £1500 inc vat and fluids before you ask

im using a fully synthetic 80w/140 diff oil

std 7.5" casing so not really much to look at.....



also should you go this route one thing to bear in mind is that the diff flange threads are a different size to std

std is m10X1.25
r+d is M10X1.5
