Drivers bucket seat 71 Duster

Bought a pair of buckets without tracks when I bought the car from same guy, was told they are A body but not from my car

Bought tracks from the local Mopar harvester, they were labeled 73-76

Passenger side lined up perfect, seat sits perfect.

Drivers side tracks were in bad shape, cut off studs, etc. one side had one weird thing that looked like a spacer

Anyway, drivers seat went in just as easy, holes lined up etc

However, the drivers seat leans toward the door. Tough to say how far but enough to notice.

Seat is not bent up and it moves as it should. Appears to be the whole seat, not just the back.

Anyway, I supposed to have some weird spacers on the drivers outboard?

Is there a major difference between my 71 and the 73-76 tracks i bought?

He said they were all similar
