My issue with the Original Air Group's kits are the bracket for the compressor, more so, the adjustment 'T' they use. It's a 'T', where the long part is threaded rod, tacked onto a piece of tube that supports the side of the compressor entirely by that threaded rod, it vibrates, and breaks in short order.

I had that problem with the kit on the 442, went through 2 of them in about 25k miles. The same config is used on their' other kits.

So I bought the Vintage Air bracket, and replaced theirs' and all is fine.

Another thing, some cars use a vacuum switch(es), and doors, to actuate stuff like duct switching and heater coolant flow, AND, those suck. (No pun intended). I went through all the lines, diaphragms, switches, etc on the 442, and here I am now getting ready to swap it over to a Vintage Air setup.

IMO, if you are starting fresh, and not doing a concourse resto, go straight to the VA setup. (Sorry for the rant, but some may need to hear it)
