Suburban 2nd and 3rd Row Seat Question

[Chad Traylor]

I have a 1965 GMC carryall/suburban. It was missing all the original seats when I got it. I recently acquired a front, middle and third row seat. The newly acquired middle and third row seats are from a Chevy suburban that mount to plates in the floor, whereas my GMC uses a channel track mounting system. Has anyone come up with a way to fit these seats to the GMC tracks or should I try to trade for seats that mount on the Tracking?
