1968 Dart Left Glass Needed.

I will answer the glass difference-- the 69 model year changed to the post at the rear of the glass for the stop-- the earlier years used glass stops mounted inside the door. so yes the glass will work -- just the stop method is different--- i would think that a 67-68 rear slide is missing the attaching bracket that stops the glass's upward movement.

I have not put my glass back in yet --so i'm not positive on the plac ement of the stops-- but my d/s glass is 67/68 version-- while the p/s is 69 version.
Luckily I kept a complete 69 door & i'm comparing hardware as I disassemble -- so I can re-assemble my convert.!!
