I cant find it but maybe you can. I remember reading that there are part numbers on the clamshells, the one with an odd number at the end goes on one side, and even number goes on the other. Just cant remember which side but maybe if you search for something along those lines you'll find it.

I would think any bolt would be fine aslong as its a heavy grade bolt and fits the hole
