Thanks for the info Joel. I called the dealer in Fort collins a little
earlier, and they had both the flange and the gasket in stock. I guess I
wasn't paying close attention to that thread earlier. Since the wind
chill is about -30 here today, I'm gonna let one of the local mechanic
take care of it. I try to do everything myself, but I don't have a
garage to work in. He's a good guy too, so I don't mind supporting him a
bit. On another note, the dealer here, though expensive, has many
competent people with repsect to vanagons unlike my experience in the
carolinas. It could have something to do with the fact that in Denver,
boulder, and fort collins, it's hard to drive anywhere for a few minutes
without seeing vanagons. In the carolinas, I could drive all day and not
find someone who had even hear of a vanagon.
So, once this flange is replaced, does that take care of it for life for
most vanagons?
