1966 Alternator mounting bracket photos wanted

Sadly to say finally having time to work on the car with this crazy pandemic. I was hoping that someone could possibly help out with pictures of the alternator mounting brackets. Also the power steering side . Received the car with nothing but a box of parts and would like to start getting it back on the road. All help would be appreciated.Also does anyone have any input why some of the bolts are notched I’ve only seen that on intakes and stuff and older cars before?
