I little more looking and you're right the alternator was lined up front to back but rotated slightly due to a mismatch between bracket, alternator sleeve and bolt diameters. Tweaked it a bit but may need to take all parts to the bench and find bolts and sleeves to match everything properly. The bracket on the engine is quite heavy duty, 3/16" steel, but the spacing on it is about 50% too wide for the alternator, thus needing spacers to fit in as well.
Anyone got better ideas than what I'm thinking?
Thanks all!
