What are the pulleys from? The '64-6 273 alternator bracket you showed earlier is a good solid piece. If the belt lines up when you use that, that's what I would use.
65 Barracuda 273 with A/C. No power steering
The bracket was in a box the pulleys were on the engine.
The belt lineup either way.
But without the bracket the alternator is lower and tighter to the block and also less weight with the smaller bracket unless it's a heat issue being close to the block
what do you think
