This is a new duplicate of original AC bracket for the Buick V6.
It holds the compressor (Yorx) and the alternator below. You use your alternator adjusting arm,
You need a three groove crank pulley to run AC.
Will not interfere with P/S as its the opposite side.
Wagoneers had the same Yorx compressors. Some moved more air so look for that one.
I can not get the original tension wheels they used, so you will have to improvise with that part of the install with something newer.
