Robert, don't feel too bad. Most vendors and aftermarket supply houses today use the "no one has ever complained before" excuse in order to cover their mistakes. I have a laundry list of items that Ames has screwed up on, but I tell ya, they're still pretty good compared to other vendors. Ames Performance used to be the best supplier of Pontiac parts in the country, but within the last 10 years, competition from other parts suppliers, especially those that specialize in bringing cheap Taiwanese made parts to our hobby, have forced Ames to struggle to become noticed, and unfortunately they've become "just another choice" when looking for a specific Pontiac part.
It's a crap shoot with parts suppliers today. Quality is so poor, and yet people continue to settle for mediocraty. That's America. With the Musclecar market now in decline, we're going to see a lot more "catalog mistakes" and cheap Taiwanese knock-off parts flooding the market.
