The seat tracks should be identical for any "Similar type seat" (buckets if you have buckets, etc) from the following:
Lebaron (4dr and wagon)
Lebaron convertibles 84-86 (ONLY IF your car already has bucket seats).
Some "could work's" are:
Lancer/Lebaron GTS: I took a pair of front buckets from a GTS and put them in my daily driver Dodge 600ES Convertible. The seats worked ALMOST (GTS's are 4dr's, Convertibles are 2 doors so they don't 'move forward') after I took them off the track for the GTS and put them on the tracks for the 600ES.
I have a lot of other suggestions, but instead of going into it all here I'll just say that if you're interested in more please PM or Email me. I'll be happy to bore you to tears with all the options I know can work.
