Just after this last post I pulled the radiator out, had it "fixed" and put it back in. Drove it 4 miles and it leaked again. This was really my own stupidity. A new aluminum radiator is only a couple hundred bucks and it's a pain in the rear to pull it out and put it back in. I ordered a new Champion radiator (I've got one in my square body and love it). I hadn't touched the truck since. Life gets in the way. (although I did ride my Harley 4500 miles from Mich out west especially in the awesome state of Utah.) Finally this weekend I swapped out the radiator and put the first 6 uneventful miles on this truck in decades. Now it'll sit again for a few weeks at least while life gets in the way again. (no bike trips planned unfortunately). The timing isn't quite right, the steering is a bit "floaty" and there's still pages of work to get done on it. But it looks pretty cool and really that's whats important!
