What engine are you going to use ?
If you use a Chevy small block they have the brackets for it in the "kit".
If you run a "LS" you just use the stock "LS" compression and brackets.

If you run the stock GMC V8 you will have to fab the A/C brackets and find a pulley.

I had a '56 GMC 347 V8 that was changed out for a '60 Pontiac 389 that was fitted with a '60s GM A6 compression and brackets ... Good Luck finding that today as this was done in the early '70s . It used a factory '69 Camero a/c unit .


On my current project I'm running a 2005 5.3 out of a van with all the stock accessories including the compressor and the Old Air unit inside and all vents will be mounted in the dash .
