The seller replied and said I asked him previously about the model #. I said I hadn't, so I'm to send him a note tomorrow and he'll look. Maybe he should include it in the description.
Going by memory here but I think that's a big plug that fits Fords.
Correct Carl. 18mm tapered seat. I had a 1974 f250 with a 360 and I think those are what I used. Interestingly the AC plugs would back out. I dont know why they backed out but the Champion plugs stayed tight.
