I need directions for a vacuum pump rebuild on 1981 300SD. I searched the threads and can't find a good set of directions. Unfortunately, there are several links to http://business.baylor.edu/Richard_Easley/autofaqs/Vacuum%20Pump/Rebuild_vac_pump.htm
and http://diymbrepair.com/easley/Rebuild_vac_pump.htm but they're both dead.

Please help.

Thanks.
P.S. I did find a good rebuild kit for $45 at ********az.
