Will '91 Turbo Interior Fit In '88 FC?
 

will the leather interior, seats, door cards etc, fit in a 1988 fc ?

I know the alot of the S5 parts are different, so you'll probably need to fabricate alot of it

The following applies to US cars:

AFAIK the only parts that are not interchangeable are the A-pillars, headliner, and seatbelts (because of the motorized belts in the S5). If you swap all three of those with the motorized belts, then everything will work.

If you want to stay with manual seat belts, you should be able to swap anything other than those (seats, door panels, carpet, etc.). Some (maybe all?) S5 doors have a speaker which not all (or maybe none?) of the S4 cars had; so the S5 door panels (some? all?) have a speaker grille.

For non US cars I don't know if S5s got the crazy seatbelts, so there may not be any issues

its a united kingdom right hand drive car

the b-trim pillars dont match and niether does the support for the rear bins. I just cut my s4 for support to fit.

like mentioned above, neither A-trim nor headliner fit
