My 67 Cutlass has the short rear seat (has the side filler panels that connect to the armrests) my question is; did all 67 Cutlass and 442 models have this setup? I know later 68-72 Supremes had this shorter seat, and of course convertables were different. Just trying to get the right length seat covers.

 

The 66-F85s and F85 Deluxe (3400, 3600) and 67 F85 and Cutlass (3400, 3600) had the long seat; 3800s (Cutlass in 66, cutlass Supreme in 67) had the short seat with arm rest/ash tray setups. All 442s in 67 were based on 3800s.

 

66 F-85 Deluxe 2dr had the narrow(short)rear seats as did the 67 Cutlass 2dr.

Oops, I wasn't sure about 3600s; Henry should know. Just checked the parts book, Henry is right. 3500, 3600, 3800 use the narrow seat in 66-7.
