Jeff: Thanks for the information on rebuilding the hydrovac. I haven't gone through it yet, but I fully intend to do that. It looks as if you put a lot of time into putting it together.
Scott: It depends on the store, and the clerk as to the service you get, and the parts available. Unless you have a retailer who is interested in doing more than just taking orders you are not going to get much out of a Carquest, or NAPA, or any of the other regular auto parts stores. For example: I know NAPA can get a lot of parts for these older vechicles, but most parts clerks either don't know how to find them, or don't care enough to look. I have had some luck with finding rebuilt parts from NAPA, but I have also been told at other stores they can't help me, with the same part. I agree with Shop Shark. It's easier to deal with some one like Jim Carter, who does care about their business, and won't get belligerent when you take him off the phone with his girl friend.
