Hey guys! Would swapping differential gears from different cars be something to DIY or better to get done professionally? Planning to weld the final ratio once its in the intented case but a bit hesitant since I've heard both that it's DIYable and some suggest to get it done. Some youtube tutorials make me somewhat hesitant aswell. Planning to swap E39 3.64 gearing into a E46 188 differential case and weld it for skiddos. Any ideas and suggestions greatly appreciated :)
