July 10th Polished the front side of the heads (these had small scratches on them, so I sanded and polished)
Week of July 18th Been working on the brackets and such.
Cut the wires to fit to make them clean looking as possible. Hard to do on a Ford.
No spray can here. All black parts were sprayed with SEM Hot Rod Black which is a very good catalyzed urethane. All parts were also sandblasted and sealed before painting. Power steering pump is on the way. Going to spray it the original dark blue metallic color.Decided on going with an updated Sanden compressor along with a parallel condensor for the a/c. Love to see it get 40-45 at the vents.

July 21 – Finally got the evaporator case installed. Took the case apart and took the evaporator in to get it checked out. An A/C shop said it was fine.
I polished the main lines of the evaporator. Need to get a new expansion valve and POA valve.

My original pump on the left. I mixed up some paint to match the original color they used on the power steering pumps. I made up a basecoat/clearcoat. The original was a single stage paint. Notice the factory run.
