Called my ex-mech (since I do 99.99% of everything now, ha) to ask for a referral to a rad shop to flush/refurb the 280's rad. After teasing me for a few minutes for bringing home another old Merc orphan, he offered me a fuel-injected '78 m110. 100k miles on the clock, and was in for a blown head gasket when the owner abandoned it. Taking the truck down tomorrow morning! All I need to do is source a harness and electronics - lol.
Sorry...I'm so excited that I had to brag to someone...and the wife is sick to death of hearing about this car...
