Dovetail Plate

Would the following dovetail plates and rings fit either a cg5 mount or the Lidl mount - www.astroshop.de/en/telescopes/accessori...-5-6--mounts----long (the dovetail plate) and www.astroshop.de/en/telescopes/accessori...90mm-inside-diameter (for the tube rings)

(The above is to fit a WO ZS80mm onto either of the above mounts)

I'm thinking these might be too light and that I'll have to go for the Vixen style plate.

Any advice welcome
