Just thinking about welding the diff in my ST141 Corona. Not a daily, it is an unregistered skidpig basically and i want a locked diff for better skids as i might be taking it to wakefield park in december for burnout warriors. I want to know the best/easiest way to weld the st141 diff. It doesnt have a removable third member i dont think, does this make it any harder/more confusing to weld? Any advice and tips from anyone that has maybe lock welded one of these diffs would be much appreciated!Cheers !
