im still workin on my motor on my 64 riviera ..ne1 know where i can get a book or diagram of where the vacuum lines go ..some broke they were so brittle..:eek2: like the heater blower one ??
dont know if youve tried Ebay or maybe the buick farm web site or even Cars inchttp://www.oldbuickparts.com/. Ive gotten good books from each of these places. A chasse manual for your car will have all that stuff in it too.
I would highly suggest joining the Riviera Owners Association. You will have all the references as well as tech advisors you need at your disposal. The membership dues are worth the magazine (Riview) alone. There are tech articles on just such things you are asking for. You should also consider picking up a chassis manual. I'm sorry that doesn't directly answer your question, but in the long run I think that is a "better" answer that will ultimately get you what you need- and then some. Erik
