Help with my Supatrak Mount

[rickj]

I have a Skywatcher Supatrak mount that originally came with a 80mm Mak attached using a clamshell. I now want to use this mount for a different scope but having taken the clamshell off there is no way to attach a dovetail. Any idea of what part I could use? Thanks

A spacer with a dovetail bar bolted together using the existing bolt and nyloc nut. Tube rings on the dovetail bar for attaching the telescope. The spacer is to clear the black housing.
