I was positive that my '67 was a Camper Special, but I wanted to make sure before ripping into the rear hubs. I was quite surprised when I got my Marti report that it was a special-order truck, with heavy-duty springs, but not a Camper Special.
Moral of the story: if you really want to know about your truck, get the report. I think it cost twelve bucks; I put more in the gas tank.
