Heater A/C control valve vacuum switches and part numbers

I am having trouble with the parts manual understanding the part numbers. I thought the 70 was differant than the 71-72 for the water control valve? From my searching google I am not so sure now. I want to replace both of these because i don't want to chance these going bad. They test ok but I don't want to discover a vacuum leak after a short time of driving it. This car is a 70 that has console and 8 track and A/C. It will not be an easy job to change later if it goes bad.

Does anyone know the correct parts and where to get them?

I am away from my parts manuals for a couple of days but will look them up when I return. I thought there was a parts manual available online somwhere although I cant remember where.

Eric,
This is what I found

68-72 F85 7303062
valve, outside air door cont. vac (on cont.) *I think "cont." is short for control

70 F85 7311528
valve, vacuum hot water

71-72 F85 CAC 7933868
valve hot water

This is from Sept. 1972 parts manual. Group 9.275.
Hope this helps.
