We used an Allen wrench to hold the shaft and a socket to turn the nut and secure the alternator pulley in place. Once done, an O-ring-equipped cap made it all look good.

The bracket assembly was then used to put the Sanden compressor in place. Note the lower two holes use two long spacer sleeves.

Just to get an idea for how it will all look, we went ahead and installed the block for the A/C lines. They route under the A/C compressor and exit just above where the heater lines go on the water pump.

The Sanden SD-7 compressor was supplied to us by Vintage Air, but is normally part of the Concept One kit. It bolted to the earlier head bracket using a small spacer. There was a small widget in this hole on the compressor we needed to knock out so the bolt would fit through.

Mark this as done. Installation took well under two hours and was easy and drama-free. We really liked the overall fit of the kit, and its fairly compact design. The high mount of the A/C compressor will ensure it doesn't hit our Chassisworks subframe when the 495hp 5.3L LS is eventually dropped in place.

Concept One includes this cover to dress up the compressor. After all, there's nothing wrong with a little bit of form along with your function.

The Goodyear tensioner was then secured to the A/C compressor bracket.
