Crank bolt specs needed

I have a 352 out of a 1958 TBird. I need the bolt that goes on the end of the crank and holds the harmonic balancer on. Can someone tell me
its diameter and thread pitch? (and maybe length?)


Since then I have learned the bolt is 5/8" with 18 pitch and 2.050 length (not incl the head). The remaining question is what the diameter and thickness of the washer are.

Washer is part # B8A-6378-A, 1.76 OD, .66 ID, .212 thickness.

ARP sells both crank bolt and washer. Jegs, Summit etc....
