I have a SSP box in my 1975 Super. Does anyone know what the gear ratios are and the R&P? I see that some VW boxes have a LSD ex-factory - does this one also have one? And lastly, should one have it modded/strenghtened for a powerful street engine - if so, what would you suggest? Thanks

just drive it until you break it, then get it rebuilt.
I ve had a used ssp 3.88 in my bug for the past two years and its doesn't mind 180HP
