The Vern Tardel motor mounts finally showed up and I got them installed last night. I will be replacing great looking hex head bolts with a round head something. I still have not found a rivet head with threads bigger than 1/4" so it will more than likely be a slot head. The engine has about a 1 or 2 degree rearward slope now which I can live with. Some people say to mount the motor flat with a torque tube and some say 3 degrees so who knows.
