    Still putting pieces of my 72 together. It's been a long time since I pulled the engine out of the chassis and I don't remember how the mounts bolt to the frame crossmember. The mounts are threaded for a 7/16" bolt, but the crossmember has a 3/4" hole (approx)? What gives, am I missing some pieces or just a few marbles?

    as I recall (its been awhile for me too) there is a big hole in the crossmember that is supposed to give you access to the bolt that connects the mount with the engine. around this hole should be 3 smaller holes that are used to bolt the mount to the crossmember. hope this helps

    Well, Im not at home right now to look at it, but there are three bolts countersunk into the rubber part of the mount that are used to bolt the mount to the engine block. Then there is only one threaded hole 7/16 in the mount where it bolts to the crossmember. Is there another piece to the mount on the other side of the frame crossmember? Holes line up, but the 7/16 bolt is swimming in the 3/4 hole.

    This larger hole is so it will be easy to get the bolt in, plus any differences in parts. It has a large thick washer to cover the large hole. Hope this helps.
