Tried to post on this subject once so if it shows up again sorry.............JeffTheMarine wrote:I am pretty sure that you would have to use the sweptline seat tracks but I would assume that they would have to fit since the other truck that the member posted had them. I know they are a lot more common in the mid to late 70's trucks then they are in swept's. They are still not incredibly common but easier to find I am sure. I will get some pics of my truck up soon. It is half sanded and half primered as I am taking care of all the surface rust right now. I am not sure if I already mentioned that.

John is correct.......they are Original Adventurer buckets. I'm not sure about the 70's seats but these are mounted to a single frame and operate as a bench. They do not operate independently as most buckets do........again not sure about 70's. Here is a link that you can go to http://www.sweptline.com/hist/css.html and if you scroll down to the CSS/Adventurer package there is a good picture that shows them. I'm not sure how rare they are but the guy who recovered them has been in business for 45 years and had never seen a set. After I brought them to him he still was not convinced. Only after finishing was he convinced they were the real deal. Seen a very rough core on ebay a year or so ago that was at $300 when I looked.....not sure where they finished.
