NO holes on 283 for AC Compressor

I am trying to hook up a Vintage AIR AC unit on a 1967 283 SB Chevy. However, there are no holes on the passenger's side for a bracket. Is there an alternate mounting bracket for this application - maybe hooked onto the water pump bolt?

Maybe......Not sure of the AC setup on the earlier cars.....Starting in 69, when Chevy went to the long water pump, the heads had the extra bosses and mounting holes for the passenger side mounted alternator........If memory serves me right, the AC compressor was in the middle above the water pump...but I could be wrong.

Vintage Air should have the proper brackets for mounting on a pre 69 SBC, give them a call. Whatever you do, do not take anyone's advice to drill and tap the early heads. 9 times out of 10 it won't work and you wind up with unusable heads.

All the vintage air systems I've seen take into account that the engine doesn't have mounting holes in the heads, if the system was designed for a car that shouldn't have those heads.
My '64 El Camino mounts the compressor by the exhaust manifold bolts and the water pump bolts. There were spacers provided in case headers were installed.

You could get a catalog from Bill's Hotrod Company 1064 E. Edna Place, Covina, California, 91724 phone 625-332 1915. Good people, good prices, great brackets. I have no conection with this company. Dave 39
