I got the EGR reinstalled, and started it up. It was smoking badly off the exhaust manifold, right in the center, so I tightened the valve cover a little more and it stopped.
I removed the old tires, which were so dry rotted that 2 of them would go flat in a day or two. I reinstalled a set of Firestone Firehawk Indy 500 tires all the way round. After getting the new tread on, I ran it up and down the street 4 or 5 times. The brake mastercylinder rear compartment is empty and you can tell that the brakes don't work properly. After getting back, I checked the rotors and only the front are shiny. The rear aren't working at all, and likely need rebuilding. The front needs pads, but the rear are good.
Here are a few pictures after it got a wash, today. Before and After pictures. The after pictures are what I hope it to look like when we get it ready to lead parades and to loan out to members.
