You are looking at the alternator brackets from a 70 Olds 442 455 V8 with without A/C. The upper bracket does not match what I would expect to see as a correct bracket but I know it worked fine. My research shows these brackets to be correct for 68 to 77 Cutlass & 442 with 350, 400 or 455 withOUT A/C. The lower alternator bracket is stamped 397209. This setup mounts the alternator on the left side. These brackets are in good, usable condition with little or no pitting. Hard to find non-A/C brackets. Freshly bead blasted.
