bbody 72-74 could be other years also but they are pictured in my 73 parts book. Looking to male a good deal on them?
They don't match the A body ones in the add. If you look at the e-bay add, the A body ones have the z profile when looking at the end while yours have the C profile.
The 70 seat tracks seem to both have the C profile like yours do. I would say that's a closer match. If that's the case, those are a one year item and worth a little more. Try to get some dimensional information on the 70 tracks.
I cant tell you what they are from but I can tell you they are NOT 73-74. I'll post pics tonight of the passenger side set I have out at the moment... the Drivers side is almost identical just opposite.
The biggest difference for 73-74 is the center tracks nearest the console are tall like the ones in your pic but the tracks near the door are very low with almost no stand off the floor.
Will post pics tonight
