I've found two extra sets of the white spoke steel wheels that fit the 1980-89 4 lug hubs. I have no idea of how rare these wheels are. I made a quick tour of local wrecking yards and found enough to meet my needs. I left two sets still on junked subarus.
I don't know if these are difficult to find or not. IF they are in demand, I'm willing to go back and get the 8 extra wheels and sell them here for a reasonable price.
IF they are pretty common, I'll just pass on them and let someone else "find" them.
Let me know if I should go back for them.
