These were the only two I saw this weekend.
This one is a 1969 GMC. It was already sold by 10 am on Saturday morning. Here is another view.
This one was not for sale. I am not sure what year it is. It was sitting on the backside of an exhibitor's booth. Looks like it still a regular driver.
And here are two views of a Comet. I dont' know what year and I doubt they came with this much engine, originally.
