Longshot Wanted Ad for 10" GSO Imaging Newtonian Aperture End Cap

I need an endcap from a 10" GSO Imaging Newtonian.  This is the end ring that is placed over the raw cut of the steel tube.    I rebuilt my 10" with a better Hasting's aluminum tube and better secondary and primary mirror holders and need something to cap the raw cut on both sides of the scope.   I have found that the end cap from the steel tube GSO Newtonian works perfectly and am looking for one to match the one I salvaged off the original scope.   Let me know if you have one.

Thanks
