Hi,
I recently bought an old, slightly rusty 1985 300d previously owned by a punk kid who destroyed the vacuum line system. My turbo no longer kicks in and the car takes 60 sec. to get from zero to 60 Mph. My research points to insufficient vacuum, but if anybody thinks differently please tell me.
I want to rebuild the system but need to know What sizes of line, kinds and quantities of junctions, and what other things i will need, also where to find them online.
Also my passenger rear window very occasionaly will work great but otherwise does not respond to the front or rear buttons.

Answers would be great. My haynes manual is on the way so there is hope.
