Here is a shot of the rear a/c unit. I'm replacing all hoses/fittings and hope to get all back to OEM functonality.


After a couple months on the road and later a bout with the 'plague' I'm back at it. Here is the 25" pusher fan (second try to get it right). As you can see I'm using an electronic fan clutch that Duramax vans used. Unfortunately, the LBZ PCM doesn't support the fan clutch so an aftermarket controller will be used. Because the controller is built for electric fans it will not be able to modulate fan speed. It will act as an on off adjustable temperature control with manual over ride.


Used some aluminum I had for the bracket.


Got the throttle pedal mounted.


Close quarters.


Top side view. Unlike some of the previous builds, my shift cable will pull oposite the OEM shifter. I plan on using the column out of the donor truck which reverses the FMC's shifters pull direction.


Another view.


A look at the shift cable bracket.


Here you can see the isolation mounts for the heat exchanger. Finding high temp, oil resistant mouunts that can be used in shear was an issue.


here's the CAC radiator. The radiator extends below the door lovers (the aluminum horizontal you see ) so I'll put a few openings in the lower fiberglass for more air flow

The fuse panel location is pretty much dictated by the harness length if you don't want to lengthen a load of wires. You can see the engine PCM as well as the transmission computer. I used a PCM mounting bracket from a Duramax Van and the stock fuse box from the donor truck. Busy corner.


This is a new access door for the front HB. Too bad 669 didn't have one before.
