P/S and vacuum pump upgrades?
I have a 91 D350 DRW. The P/S and vacuum pumps are missing. I heard the early 90's engines had a poorly designed vacuum pump prone to failure. I want to know what year pumps will work as a upgrade and what is involved in upgrading if they are not a bolt on replacement. Thanks for the help.

The newer 1st gen pumps will bolt up to the engine OK. I know '92 and '93 pumps are the new style. Good luck finding an affordable set, those things are really expensive.
