I could always grind the shoulder of the bolt down if I had to so it would seat.

I don't think I would do that. I do believe they are an interference fit. I can't remember when I did mine. I do believe they went in tight.

They need to be snug, you don't want the ring gear walking in the slightest.

Try and tap one a little with a hammer and see if it seats. You said you have extras so you can always knock it back out and use another new one.
