F5RZ-17285-AA speedo gear- F7RZ-4221-AC diff bearings, you have to order 2 bearings and I don't know the number for the shim pack. It's around $100 and it's the only one available for the MTX-75, if you're a good enough explainer you should be able to walk the guy in parts through it enough for him to find the pack. Straight from the mouth of Terry Haines... 'get the ford service CD'. I got it and it will walk you through a complete mtx-75 rebuild.
