These diff are specially made to suite the AMC ride on mowers.  Plenty instock at the moment.
The bolts are also special HT bolts with the exact amount of thread.
These diff housings are made on the premises and may need to be pre ordered depending on demand.  No internals.  These can be purchased seperately, pleae note we are a bit behind due to the lathe needing repairs.  Hope to have it up and running again soon.
We also rebush your diff if it is in good condition.
