1955 Ford F-100 w/ 67' 273 & 4 speed

It had A/C installed on it. Im not sure if it is an aftermarket bolt on kit or if it was out of the barracuda. It was a york compressor seemed the be in stock mounting locations.

It's an aftermarket.

Can anyone send me a close up to show me how the alternator is supposed to mount? There are two potential holes that can be used to mount the alternator.....

From the photos it looks like the alternator is in the stock mounting location.
