The supplier depends on 1 of maybe 20 rebuilders for the industry. 95% of the time what store A through F has in stock at one point in time, usually diminishes or is an on demand from a wholesale hub.
I recommend calling NAPA, Autozone or Advance Auto and asking the specs. What master I bought 2 years ago at NAPA may or may not be available.
