Hmmm, I haven't had to cross that bridge yet. I was able to get a fuel pump by crossing out a '57 400 series at Carquest. My local Carquest has been there for about 30 years and have some paper books in the back room that go way back. I think GMC used the 302 from '52-59. They were also in military duece and half truck during that time. 302's are also popular with the hot rod crowd, so spark plug wires are out there.
Perhaps some one who knows a part number will chime in soon.
