Muggy diffs in a maxx

This is the t-maxx I am in the middle of building, I have fitted up a pair of LST2 diffs, I machined the side spacers and diff collars myself, the front one has the extra clearance under it to clear the proline steering links. I decided to spend a little time on the lathe at work as it seems collars are the weak spot when opened out for the lst2 diff (hopefully these will hold up ok)\
