I'll probably give you a couple of hundred if they're not chipped/cracked and actually work. And are genuine subaru ones (if you can get copys?)

If you're a real chicken man, you'll know these are as rare as hen's teeth ! :D

No-one makes them, no one wants to sell them, and you're only course of action is to persuade your local Scooby garage to flog you a set.
A P1 Chassis Number usually helps convince them.

Best of luck!
