Thanks for the reply Mugsy. I went to AutoZone today and was told that both parts are discontinued :mad: . I went to Napa and they were able to cross-reference the AutoZone part #DV435; there was no cross-reference for the other part. Unfortunately, the Napa (Echlin Part # VC1858) part was incorrect :mad: :mad: . It looked as if it was for a SB Chevy rather than for a stovebolt. Thanks for the advice about buying a rebuilt distributor; however, I really don't need one since the one I have only has about 3,000 miles on it. I guess I will have order a vacuum advance from Jim Carter or Chevy Duty.
Luckily, it is almost winter storage time and I will have the time to stew over this all winter.
