Can '81-84 sport seats be used in an '85 Carrera?

[Reddy Kilowatt]

I'm trying to increase my headroom a bit. Are the older 81-84 seats a bit lower, or is the difference between 84 and 85 seat height only in the rails? And will the older sport seat work? Is it a straight replacement, or is any modification required between the sliders and the seats? Thanks!

I think you will be just fine both are model Carrera, should have the same base rails.

I would measure the seat rails against the base mounts. Take a note of the rail positions, they are not even at the rears.

Straight replacement.

80-84 doesn't have seatbelt receptacle on sliders - they are floor mounted in those cars.
So when you say straight replacement Mclovin - are you swapping rails from the 85?
I'm interested in doing this myself

Easy fab job for seat belts swap. Def sit lower in the seat. I may have some cores avail for cheap if looking for manual sport seats?

vintagecarlover - I'm gonna try a fixed Sparco and if that doesn't do what I want I'll PM you

You can't easily remove the rails from the '85 seats. You would probably buy an adapter from brey krause, or I believe there is a factory part, that is sandwiched between the rails and the seat that provides an inboard seat belt mounting point.

Edit: see BK R-9005 or this thread for factory part.
