Correct motor mounts brackets for 340 .. Help !!

They can be tough to find, and pricey.
If I remember right Rob aka Crackback makes them out of 318 brackets ? Check with him.
Put a search here on the wanted adds.
Ebay, Google, etc.

You will probably have to buy a pair if you get them online anywhere, I'd expect to pay $140.00 give or take.
