Whats up guys I have a s13 with a j30 diff and 5 bolt axle setup with the stock 3.916 final drive ring and pinion. I would like to have the snappy gearing and could not find anything about swapping in a 4.36 final drive ring and pinion into a j30 differential. Would this be a direct swap or would I need different output shafts any advice would help thanks.
