This outfit has complete kits or the parts to assemble your own. I bought the inside evap/ heater/defroster unit, compressor, and hose kit from them and used a condensor/fan unit from an Isuzu trooper. I fabbed my own engine to compressor mounting brackets because I could not find one any where. My engine has an regular fan but I can operate the extra fan with a switch or it comes on with the ac. The evap unit sat in the garage years before I actually put it on the truck and it was defective. I explained my predicament and they warrantied it after it was years out of warranty. The fan is a little noisy on high, other than that, no complaints.
