Would you know where to find 3 pin dipped resonators/bandpass filters for 110MHz to 140MHz ?
Like these (which are 87 to 108MHz)

Or, any trick to shift their response ?

 

SAW ceramic filters are designed for a given frequency. You cannot shift the bandpass frequency range.
You can read more about ceramic filters here:

Propane torch.

For sure that will shift the center frequency a bit?

(joke)

 

88MHz to 108MHz is the FM broadcast band that zillions of radios play. The people who make the filters make lots of money.
110MHz to 140MHz is the aeronautical communications band that only a few airplane radios play so nobody makes the filter.
