Hi all, could I please get confirmation on my thermal det dimensions?   I'm building a new one to meet Centurion standards and I found lots of text info, but not a clear diagram of the latest dimensions. I can do a graphic if that's helpful for others.   Length - 7 1/2" approx. 187mm Pipe outside diameter - 2 3/8" End caps - 20mm Gaps between caps and control plate - 12mm Control plate - 122mm TD clips - The CRL says 1" but I've read threads saying 1
