I have a '69 Chevelle 4 door with front bench (UNsplit) seats. Year One offers bench seat covers for '4 Door sedan'
Part #:CF069M10B

But for half the cost they also have bench seat covers for a '2 Door coupe' same year
Part #: SF069M10B

Granted the latter are for a 2 door instead of a 4 door, but does that really matter, aren't the bench seats pretty exact in 2 and 4 doors?

Also, as far as sliding tracks, looking to OPG for new ones, they say I need 2 pairs of tracks?? for a bench, but the bench only rides on one set right? Each slide on the outside, next to the seatbelt retractor. My stock bench only has one adjust lever on the driver side, thats supposed to move the whole bench I believe.

Four door front seats aren't hinged to tilt forward like two door's are. The 2 door covers are probably cheaper because they sell way more 2 door covers than 4 door ones I would think. The track thing must be a typo. You are correct. Bench seats only have two tracks. One by each door. That must be for bucket seats.

Ah ok, I keep forgetting some have the seat tilting forward thing going on. As for the covers I figured as much, 2 doors are more common. As for the seat brackets thanks for the reassurance Jon, worst case scenario I buy another set, but not unless I have to! ;)
