Jim - welcome!
I am a fellow WSP SSP owner. The 86's are somewhat hard to find. Have seen a total of 4 over the last decade (your's being the 4th).
I will look for your post over in the 83-86 section. Would love to know more about it.
Basically, here in WA, if you have a car with no title, you can register it with the WSP/DOL. I believe it takes 2 years to file the claim. If no one comes FWD claiming the car, you can have a title issued.
