I agree Don, but I feel the problem is that at what point do you say enough is enough....converting a A/C system to 134a is mucho bucks....I'm sure Bill could save on the labor doing it himself but its far from a easy job. At what point do you say "Forget it" and just try the conversion from a cost perspective.
Between the tranny he'll need and the a/c components, he could have a newer model Bonne (not that he wants that, but I'm just thinking strictly from a cost perspective).
I agree his car is too nice to do a hack job on, but there is also the $$$ side of things too
