Those sliding brackets are most likely from a Suburban; IIRC the truck bucket brackets are all stationary on the right side.

I need to figure out a set of right side brackets for my crew cab, and I will probably let go of the pickup brackets I have. The floor pans in a crew cab and pickup are different, and it seems like a shame to cut up a set of brackets I don't really need to. I just need the time to get to a pick and pull.
