Finally back in the garage to work on my '55 series 2 with a 350. I don't think this steering column is the original in the truck, and I'm trying to find more general information on it. I'm also trying to buy the seals/sponges that go around it to help keep engine odors out. The column is 1.8" and the shift column is .7"
