Hi I'm currently putting LST diffs in my T-maxx and was wondering if yours are still holding up well. Instead of using the PVC like you did I thought i'd try to just chop up stock maxx diff cases to make them fit correctly. So far it will work. How thick is the gray piece of piping you used? I was also wondering how you got the diff to prevent from spinning? did you dremel out a stock diff collar to make it fit the LST diff?
