1 pair of Vixen rings, dark green, for a C8 tube assembly or other 8 7/8 tube diameter, will bolt to the Super Polaris mount with the two standard knobs.
Vixen dovetail bar and dovetail receiver for C8 tube. Note this is the opposite combination of the current GP solution: the receiver mounts to the C8 rear-cell by existing screw-holes, the dovetail bar mounts to your Super Polaris mount in the standard fashion, large attachment knob on the receiver holds the two together and allows fore and aft adjustment for balance. Same color as the rings.
All these parts are nicer than the current clone hardware.
Very good condition, $100 for all above, shipped in CONUS. Paypal preferred. No photos.
