1968 AC equipped confusion

Pictures of my '72. Vac and water valve.
That valve on the internet sure looks different. I am down for the count with a very bad case of Shingles. I had Sue go out and take the pictures, no part number around the top of the cannister, guessing it may be under the mounting bracket. You may end up cross matching parts.
My car is 3 years newer but ask if I can help. My A/C system is complete.
