What would you expect this to cost for parts, and about how much time for a competent mechanic?

Is this as simple as putting the car on a rack, pulling the pan, unbolt and bolt. with a bit of cleaning?

Since the olds pump lacks a vacuum component, do you still have wipers? As it is, even with a Fichter (did I get that right) rebuilt window wipwer motor, action is decidedly lethargic......
