Ive been wracking my brain on how to convert my M5R2 to RWD. I’ve heard that just the tailshaft housing needs to be converted, some have said the mainshaft does too. But I havent found any part number that differentiates the RWD and 4x4 Mainshafts. And visual inspections of photos of mainshafts from ebay ads yields no obvious differences
