Let's see. I can't seem to post the words and the photos together. So I'll try to post this -- and come back and edit it. So, any way, it was 1972 and I was helping my friend, Phil Stevenson, run his 1955 Chevy Bel Air Wagon at El Mirage. It had a 390 Cadillac with a Jet-Away Hydramatic. Not much of a drag racer, but he did drive it to El Mirage and we'd take the mufflers off and run about 120+ as I remember. He wanted to go to Bonneville and had bought a 6-pot Offy manifold for $15 at a swap meet after convincing the seller that he was the only one in the world that wanted it -- and it wouldn't fit a Chrysler. I contributed a wastebasketful of 97s left over from drag racing.
We drove to Bonneville and switched to the 18" Halibrands that I now have on my 28 Mercury. One had a Bonneville tire, one an Indy. They were about 3/4-in. in diameter different, but we had a great time.
I'll try to post the photos after this post.
