There was no "application". I just knew how long and what diameter/thread I needed, and called around to some of the local speed shops until I found one that had what I needed. I only studed the rear main cap. Probably SBC,BBC or SBF. I can't help you with the rod bolts.
I had also called ARP directly and told them the size I wanted and they sent me what I needed. Make sure you ask for the nuts, as I think I didn't and had to make an extra purchase to cover this oversite. There may be other sources out there, but I haven't looked.
