Pontiac pulleys and accessory brackets are complex and just plain ugly. We recommend you pull everything off one donor car, as the brackets tend to be application-specific. Although we scored all the parts we neededeven the A/C compressor mountsfrom a 350ci 76 Grand Prix, we opted to convert to manual steering for a cleaner engine bay, simplifying the pulley arrangement. This used 64 Chevelle SS steering gear liberated $60 from our wallet. Keep in mind that your centerlink and idler arm might not work (both 7/8-inch and 13/16-inch centerlinks were used on the A-body platform).
