67-72 Black lap belts, non-retracting

[jbclassix]

So I pulled a full set of black lap belts out of a 67-72 chevy at the yard. They are not the retracting type, I was just wondering if they were worth anything. I grabbed them thinking someone might be looking for something like that. The buckles are in great condition, and the straps are Cal Sun faded.

Also got a 76-68 horn button, black 69-72 horn button, and the bench seat sliders because they were in excellent condition. Any clue on that stuff? Thanks!
