Not a single "local" parts store carries anything in stock for these cars except for a "universal" adjustable valve. Meh, no thanks. Not even rock auto or napa carry a part for it. I'm normally good at finding parts, but after quite a search and going through catalogs trying to come up with correct parts numbers that would be a direct fit for a factory disc brake car I came up with PV6070FD for $55. After I found the best price I couldn't hit buy fast enough. I found it first through NPD as PN 2B091-20AA, but they wanted $120 for it. It took me a little while to track down the actual PN for it (it does come with a bracket to mount it in the original spot).
So she sits for another week...
Weather is starting to come around too...
