POLYLOC MOTOR MOUNTS

Hillbilly unbreakable motor mounts $5.

Buy a stock mount. On the offset bolts, cut one stud off with a sawzall. Drill it out all the way through to the other side. Put a carriage bolt through mount and tack weld the head. You now have an unbreakable motor mount since one bolt goes all the way through.

If you use a nylon lock nut and leave it a little loose, then you still have a rubber mount to damp vibrations.

If you are a really cheap hillbilly like me, you just use the one you have.
