Meade 9by 50 finder on a C11?

I bought a C11 recently and have been trying to put my meade 9 by 50 finder w/bracket on it but thr screws on the C11 are placed either too close together or too far apart to connect to the C11..do i need to buy a orion/celestron finder...or is there another way to get this puppy to fit?
any help would be appreciated...thnx!
