Went through my freshly rebuilt 371 Olds with the Olds tech thread posts and the shop manual and found how the machine shop put in solid galley plugs that won't squirt oil on the timing chain and there's another one in back through the distributor hole that is supposed to squirt oil on the distributor gear. Did a little digging on this and my question is, what is the best way to correct this?? Are the plugs available and how do I remove the one in the back through the distributor hole? Also, don't know what happened to the clips for the oil pump that hold on the drive. Anyone know of a source for those??
