Hi everyone I just got an r32 it shattered a pressure plate and made a bit of a mess to the gearbox it is supposedly a rb30 box and I got given a box with it that is meant to be an rb20 box the suposed 20 box has a longer extension housing and less webbing in the case, I had a quick look on eBay for a 20 box and found a reco one that was the same length and case as my 30 box, I am new to the import side of things and don't know a lot about them. But I was wondering if anyone could tell me the differences between the boxes wether I can swap bell housings or extension housings and different strengths between them all and what bolt up behind what?
