The Classic Auto Air kit was not that difficult to install. Would have been easier with a few tweaks to their instructions, but having done it once I could do another in a day.
The problem is that they sold me a compressor (made in China) that the threads on the hose fitting crumbled into pieces when I attached the hose (by hand, not with a wrench). Cheap pot metal I guess, I just got a bad one.
No problem, they told em they would send me a replacement, bill my CC, and credit me back when I returned the defective compressor.
They sent me a new compressor, I installed it, everything worked. I returned the defective compressor the same day. Classic Auto Air got it back and signed for it. Then they shipped it back to me, and told me that they would not honor what they told me on the phone and they would not refund my CC for the additional compressor.
So I paid for a whole kit PLUS an additional compressor, plus the freight to ship back the bad compressor.
They reasoning was... "The supplier of the compressors has their return policy and I am held to their decisions. We are required to send the compressor to them and they then determine what caused the failure. On the Sanden compressors, it is always an “Installation Error”
