I cannot seem to find out where these go. The course threaded bolt on the left is 5/16 of an inch and there are four.

The wing nut square head bolt is also 5/16 18NC and there are two of these.

Thanks so much for all the help on this stuff.

Your JPEG reference is not loading so you will have to give me a useable on line link to your bolt photos.
