I added AC to my 68 Sprint Firebird last year. As far as I know the only bracket that will work on the engine is the OEM one from Pontiac. ( look for 1966 or 1967 year brackets ) You can find them every now & then on ebay or post a wanted part on this site or on the Pontiac Overhead Cam Six Forum site. As far as the power steering pump ( if you have it) you need a double grove pulley. (ebay) Then you can use the OEM stock number belts that are available at any auto store. they will fit like a glove. EM me for pictures or additional info if you need it wayne@phoenixtrains.net https://firstgenfirebird.org/forums/tmp/12756.jpg https://firstgenfirebird.org/forums/tmp/12757.jpg
