As the heading says i need a Adaptor plate and Dovetail to suit a Celestron CG5 mount to fit a Celestron Ultima 8 (circa 1992)
This OTA has a wider screw difference at the rear of the OTA so the standard Dovetail does not fit.
What i am after is the same as on this page the part#MPC8

If someone has one or can point me to where i can get one here in Australia i would be grateful.
Other choice is to order from the USA
