Suggestions on Motor mounts?

[DJDeSio77]

Hey everyone. So I've moved a motor from an old huffy to a mountain bike using the same mounts... well after some time of course they loosened... so I went to re tighten them and the cheap Chinese hardware stripped out. I'm looking for any suggestions on where to buy a decent set of compatible hardware and or mount kits. I'm running the "80"cc engine which I think is actually a 66cc. Any input would be helpful.. attached a pic of the bike in case it helps. (Nothing too pretty) lol

Just take the bolts with you to the hardware store (to match them) & buy all new ones.

A little trick that I do is to cut a shim from a old pipe to make the rear mount fit the frame better.
