Couple notes.
..The Ac compressor is a Delco circa 1989 and Alma was a builder.
By then there was a stock pile of cores and AC Delco did have many rebuilt, but new was available faster.
... Wiper motor is from a 76 or 77, which used a much better in tank pump. Originally you would get about 6-10 "swipes" with a dry blade before fluid
would get squirted on the window. With what you have now, its nearly instant, like a modern car. I run a stock bottle and bracket and a motor and hide the wires with the hose.
If youll use your wipers, you may like what you have so you do not scratch your Windshield .
