I'm not near it right now but could post some pictures later.

There is a steel trough that the rubber goes into - slots up, then a steel plate on top of that with two square holes. There are two carriage bolts that go down into the crossmember (I believe they are 3/8 fine thread) from the flat plate. On top of all this is the thin sheetmetal cover with two 7/16 carriage bolts that go down through the motor mount plate that bolts to the front of the engine.

If your carriage bolts are chewed up you won't find any grade 5 or 8 fine thread. I had to make my own by cutting down larger ones and rethreading. Search the archives for "motor mount bolts" in the last month.

The assembly manual has a good picture but my copy is very poor on that page.
