Is it gonna be a problem?

The 5 bolts are the best bolts. Wish I had a spare I'd send it to you.

That said, you can use the one odd bolt and be fine. I wouldn't want to use more than one or two of those at most. They don't have enough shoulder on them.
Its unfortunate they cost what they do. And I only need 1. But hey, that’s the way it usually goes. I’ll probably put it back together and cross my fingers.
