I can't say for sure, but my guess is that you would have problems getting it to sit at the correct focal length with the mounting hardware that that dish has. Ie the Corotor has holes on the rings, that you bolt to 4 feed arms, but the hardware on the above dish only has 3 arms, and the odds are good that they wouldn't put the feed at the proper distance from the dish. It's possible that you might be able to connect that hardware directly to the horn tube, but the rings are so wide on a corotor, that I'm not sure they would fit inside the 3 mounting arms, particularly if you got it at the right FL, which I doubt. You might also have problems adapting that dish to normal BUD polar mounts.

Also, why do you have a polar mount, but no dish? Was the dish damaged? What kind of mount is it? Some BUD mounts can easily be adapted to handle different brand dishes, while other mounts are pretty much part of and specific to the dish.

Also, what kind of receiver(s) will you use? Ie if your mount is a typical BUD type mount/actuator, most FTA receivers won't move the dish, unless you get a separate vbox to translate the DiseqC and voltage signals into something the actuator can understand. However I don't think that the VBOX solution will handle the polarotor on the Co-rotor feed, and a normal FTA receiver won't handle the polarotor on the Corotor. Ie the best way to control a regular BUD style actuator and a Co-Rotor feed, is to use a regular analog IRD receiver, and then slave your FTA receiver to it.

Also, you say you have a Co-rotor, but don't mention whether you have LNBs installed. If you have to buy LNBs for the feed, that can add up to more than the cost of a C/Ku lnbf. The CoRotor is a great feed, and I highly recommend the adaptability of going that route, however it is a much more expensive route, depending upon what you are trying to do, and you are better off slaving to an analog receiver if you go that route.
