I'm looking for a powermaster accumulator. I've been to every autoparts store in town and everyone thinks I don't know what I'm talking about. They all try and hand me an A/C accumulator. I've seen the writeups at gnttype.org and it says they're $60-$70 and it even gives you a part number. When I look up the part at any of the autopart websites they can't find it either. Anyway, where does everybody who replaces theirs get them?
