For a 10.7 MHz crystal filter the input and output impedance specified by the manufacturer is 3.0kohm but the circuit requires 330ohm input/output impedence.
Now how or what kind of resistive network is required to match. Should the resistance be connected in series or parallel? I don't know the equivalent circuit of this filter.
I would not recommend a resistive network for filter matching. It will increase the insertion loss.
Try an LC network.
A small software as WinSmith or RFsim99 will help you.
