Yes, The coil of copper with aluminum fins. Thirty two passes of copper tubing to be exact. The evap measures roughly 14" wide by 8" tall by 4" deep. It's pretty large and is more than adequate to cool the cab I'd think.

The bottom of the box that houses the evaporator coil is easily removed once you remove the passenger kick panel then the blower.
The evaporator coil will drop out of the box. The difficult part is the freon lines going thru the firewall. The box has to be flexed to get the coil in place. Its a pretty tight fit.

To be honest, my AC is undergoing a serious modification. I am using an orifice tube type expansion device. The hi side entering the evaporator will be accessible on the engine bay side of the firewall. I have a few different size tubes to play with to get the most efficient cooling.
The receiver/drier in the hi side will be replaced with an accumulator on the suction side. The accumulator I'm using is a $24 GM part. GM R4 compressor pumping R134.

My fingers are crossed...

Hardest part is getting the evap in and out. I was just wondering what the standard procedure for the job entails.
