Hi all

I am currently trying to source a manual 5-speed for my RV8, which currently has a 3-speed auto lump stuck on the back of it.

I was wondering whether a V8 Freight Rover or Sherpa manual box would be a usable alternative. I have read somewhere that they are heavy duty D code boxes and have different heavy duty bearings on the layshaft. I dont know if this is correct however. Do they run a lower gearing, or is that taken care of purely in the axle ratio's?

My main worry about using one of these boxes is that if its come out of a commercial vehicle, it wont have had an easy life, and will have probably have "to the moon and return" mileage on it.

Anbody got any advice or experience of these as opposed to the standard SD1 gearbox?

Cheers

Marty
