†For the oil pump to block safety wire bolts: There appears to be no rhyme or reason for the pattern of safety wire. In some cases cars had all the bolts safety wired and others maybe only half. If you have less than all drilled bolts, it usually had them wired as pairs either vertically or horizontally.
