Are you talking stock GM compressor, mounted to the low right side?.... if so, the space will be tight with the standard hose adaptor plate due to the take off angle and the gear linkage on RH rod link... I'm in process of machining up a one off to fit. Will post pics later this week when finished

If your compressor is elsewhere, I'm not sure.... but try these

GM didn't invent AC so will be using standard stuff that should be available from any large AC company.
There may even be a range of fittings as the sapace issue will also not be unique to our install.

Somewhere like this.

Got this reply from Mast Motorsport going to order a set, will let you know if they fit

The manifold fittings you will need for your AC compressor are available from a company called “Doc’s Blocks” they are at www.docsblocks.com

The part numbers for your application are ;

AA0738

AA0739



This should be the items you need. Let me know if you have any questions about this.

Question ?

How many cables go to the GM Original LS7 Compressor ????

I have a GM Engine Swap book that says and I quote " The factory AC Compressor is a Climate Control unit and thus runs all the time when the AC is on. The compressor does not turn off and on when the AC is running, and this stile of compressor only works with the late model Factory-stile AC system"

Basically there saying the lines will freeze up as the Pressure switch in a old school ac system would normal turn off the compressor at a certain pressure....

I don't know the GM compressor, so don't really understand why, as if you connect a Trinary Pressure switch in the line (normally in the drier bottle) then you could still turn it on an off..
I was under the impression that there maybe some form of internal plumbing in the compressor to offload duty when its not needed...(normally called a Capacity slide in industrial compressors)

So how many cables go to the compressor ??

I had a look when over in the US and wasn't convinced there was enough space between the AC comp and gearlinkge rod to come directly out... also need to consider if you've not actually fitted your engine that the standard low right side compressor fit will foul the chassis/engine mount if you want to use off the shelf stock GM fittings.

I spaced my AC comp out 35mm using machined fittings, fitted slightly longer AC belt (4PK 1120) and knocked up this adaptor to ensure adequate clearance. Have pics if anyone interested.
