73 Dart Seats and Tracks

All,

Good afternoon FABO! Hi I'm in the need of some seat tracks for my Schwinger. When removing them the inside tracks for both sides barfed out the plastic runner and the roller etc. The tracks were very hard to scoot before removal, as I continue down the rabbit hole on this car I now need a solution. There are the ungodly expensive new ones for 400.00 or so, but all of the sources say up to 72 model year.

Can one of the experts here identify these seats and/or also tell me the interchangability of model years? In comparing the online photos of the tracks they "look" the same.

Also is there a kit to fix these? The outer tracks and spring assy appear to work good after some lube and cleaning.

Thanks,

Marion
