Alright I think my solution to the one upper motor mount tab will work out just fine.
As you can see it is bolted down to the cross bar that the tabs are attached to so the engine can be secured.
While sitting there trying to decide what my next step was I thought about my battery box and got to wondering how close the muffler would be getting to it. So do any of you think it being this close will cause an issue? Mind you the battery box isn't mounted in its final position yet until I know how the chain will run to the back.
