You may want to post over on the OHC6 forum. All of the items you are looking for are not easy to come by. There was a posting on the OHC6 forum a while back to take some existing motor mounts and refurbishing them. They were talking about getting a batch from existing owners. Don't know what happened but might be worth bringing up again. For the air cleaner, I would get a cheap chrome air cleaner from Autozone and use until you find the correct one. It could take you a long time to find one.
