Saw a friend at a swap meet today and asked him the same question & he said his friend had a B5 340 Swinger with A/C and it had color keyed wheels & red stripe dogdish caps.
(W12 14or15 wl tr rings w/hcap) no trim rings ofc on ours... Thanks for posting. Guess if you had a color keyed spare its safe to say it had dogdish on the car. (missing my build sheet, but have a factory FC7 spare though...) TX9 spare having rallys or full wheelcovers. Still may just run rallys, hmm.
Any pics of your car? How long you had it? Take it to any local shows? auto or stick. I`m not too far from you (bought my car in Blaine)
I knew someone on here had to have a build sheet with the code if they did come that way, thanks a bunch!
