Why do you worry so about the vacuum? It affects nothing on the manual, so if you have a line going to the automatic, just plug it off. Either of the two 4 speeds will work with no problems and no vacuum. Vacuum on that old a model would have been applied only to cruise control, P Brakes, door locks and engine stop. If those items work now, they will work as well with the new transmission. If you are looking for parts for the swap I have them all.
