[69-72]

Im installing a factory ac a6 brackets with ps on a 250. Im working on a list of pulley part numbers for a 250 going by the gm parts books. It’s quite difficult to decipher everything because the listings are all separated for each pulley and almost each year has a different part number for each pulley. Not all years have a listing for a pulley for AC and PS so I’m attempting to find a common year for all them. I’m just working off of 67-72 books right now My next step is to look at Camaro books. Even the 62 amp alts use different pulleys. 292 uses totally different pulleys as well it seems so I wouldn’t count on what’s working for a 250 will fit a 292.
