What bolt goes in here?

[Sardonicus]

5/16 UNC about 1-1/4 length should do ya

[Chuffmeister]

Just bolted the very same thing this afternoon!

[jojackson4]

[Bassfiend229hp]

I've bolted mine up god knows how many times and the fecker keeps coming out and disappearing.

The original that came off mine was:

5/16" (18tpi) UNC x 1", plus a spring and plain washer.

I'm glad you asked this, i'm putting mine back on tomorrow and it didn't have one before.
I'll try some high temp thread lock on it

Try 5/16UNC stud @1" long & a nut.... much easier to hook it on instead of furking the block thread trying to get it in
