Ok I decoded my RPOs today, well most of them.

Some interesting ones I found were
AR9 European Style Bucket Seats (Explains why Ive never seen any seat like mine?)
YR1 Custom Front Seats
Ys1 Custom Rear Seats

Also some that didnt decode
b9k
D6J
E7Z
FA1
FA2
GA1
GA2
NOD/N0d (neither found)
YT9
8PJ
9PJ

Any help with the non decoded ones would be appreciated. Also any idea how rare my options that I listed are? All the others were fairly common.

interesting.. I too had a few that wouldn't decode, FA1 and FA2 I believe were two of them.

post some pics of your seats, I'm curious.

I know, my car is currently a mess. But Ive never seen seats like these in any other third gens. And ive tried finding em.

I believe the AQ9 seats are the LS Conteur seats.They have multiple adjustments similar to Recaros optional in the T/A.Those are very nice seats.Those are the one option that my '83 doesn't have that I wish she did.

E7Z - Key,Speedometer (Delete)
NOD - Assembly Plant,Norwood Ohio
YT9 - Option Package,Fisher Furnished Parts

This is all I've found so far.I hope they are right and hope they help.The 8PJ & 9PJ could be the codes for front or rear springs.

EDIT:Those aren't the seats I was thinking of.The code AR9 seats are the standard reclining version.Your's just came with a different material pattern.

ah ok, I've seen those seats before in grey... nice. i didn't realized they were factory seats, thought they might have been seat covers or re-covered.

I have the same RPO. They they are fairly common. Other RPO's determine the material, colour, and if the driver's seat is power. That might be where yours might appear a little more unique.
