Alternator Brackets; 1973+ 318 with AC

Will anyone with a 1973 and up 318 with factory AC measure their lower bracket and tell me if the pump bolt to slot is similar to this one?

Also does it look like the upper bracket has all the necessary pieces. I had to find all these part individually and want to be sure. The bracket length is because the (reportedly correct) belts for the A/C, crankshaft, alternator seem to be about an inch to short.
