Also there is a metal tag that was on one of the bolts and is stamped with the # 45. Would the # 45 possible refer 45 psi ?
Thanks in advance. Michael...

The lock washers really don't matter- - - -I'd choose to leave them off altogether, clean the bolt and pump housing threads thoroughly with carb cleaner, and use blue Loctite on them. As long as the end plate doesn't get loose and fall off, the way the bolts are retained doesn't matter.
I used to cross-drill the bolt heads on the race car oil pump cover bolts and safety wire them, jut to protect that $15K engine so the driver could over-rev it and scatter it like a hand grenade!
