I have a 1969 GTO with a factory 400 and 1966 Olds 442 with an Olds w31 350. These cars have been in been in storage for awhile. I am going to prime oil pumps and engines but I want to make sure that I am have the correct Oil Pump Priming Shafts. Any recommendations as to the proper one(s) to buy? I do not have a spare distributor(s) one hand to convert. Thank You
