Rather then having to deal with vavuum problems in the future, i replaced every visible vac.line i could see.Total cost 20.00,total time 35min. After all there 14 yrs. old.

Vacuum systems for these things are the easy way out. The 600 of the '60's and '70's had power seats (front and rear), locks, sunroof, windows, windshield wipers, decklid release--all of which were not electric, not vacuum, but hydraulic. Now wouldn't that be more fun?;)

Is there any reason why you can test the vac. system with pressure, say 1 pound or so? That way you could use soap in a spray bottle to spot the leaks. I mean, finding a negative (vacuum) is not easy on a good day.
