Vac operated wipers?

Anyone have a diagram of how the cables feed through the pulleys on early 50's GM vac operated wiper system?

 

I have some for a 55 Chevy if you think that will help. Let me know and Ill send it to you.

It should be the same.
Would it be easier to scan and e-mail?
If not, check you PMs.

 

I'd be interested in that too. My '50 coupe hasn;t had wipers since I got her 5 years ago. I don't think were gonna have too much more rain in SO. CAL. this year but it's been long enough.

 

I don't know if this will help. The cables running towards the wipers just loop around the pulley.
