I took another look at the pics, and the pic showing the right rear I think I see some leaf spring between the wheel and mud flap. Haven't heard back from that person, so it's probably not for sale, but couldn't hurt to ask.

Found this '87 Raider on the local Craig's List:

Might be worth a phone call to get the miles, how many owners, address, etc. The red one had 30's on the stock 5-spoke steel wheels, and this one looks like it has the same wheels, but bigger tires, maybe 31's.

I'm still waiting to get an estimate back from the shop on what they would charge to replace the bad head gasket. Cheapest shipping quote I've gotten so far is $600.
