The Coughlin family has a great nationwide business that started here in Columbus, Ohio. They've always had or can get what I need the next day since the warehouse is up in Delaware, Ohio. Their facility is state of the art, and I have a retail store just a few miles away.
One thing they were known for was not good. I had heard stories of them loosing the parts you brought in to have worked on. And it happened to an old friend. He had taken in a matched set of heads for an original numbers matching '69 302 CID Z28. Yep, you guessed it. They wound up missing. He received in turn a pair of the correct heads, but the were not date code correct. But that was in the past, and I don't know if the claim of missing parts is still valid.
I'm still debating which convertible sub-frame connectors I want to get.
