<BR>I have the print at work and will post ASAP.
<BR>The threaded portion of my inspection plate is 6" Dia. I called Perko and
<BR>found the plate is still available and can be ordered separately. I had to
<BR>order it through Defender. I believe you can also find the plate in either
<BR>chrome or bronze at Perko Web site.
