I actually hadn't even threaded anything in the holes yet, but just did. There is another hole that needs heli-coiled on the opposite corner, a bolt threads in but the inside looks iffy to me. Looks as if the p/o didn't use long enough bolts. The heli-coiled hole is fine though. I'm thinking of drilling them all for the next size up and retapping them.
