Here's a few pics of tri fives on car haulers I've saved. The pic of the 57's is a little small but it's the only pic I've ever found of the 57's on a car hauler. Form all the pics I've seen they were usually pretty random.
There was a post on here last night with someone asking to Identify a model of a dirt track car with 50 ford cab on it. I thought it was in this section, was it deleted? I've looked through the forum and can't find it.
