   I haven't looked at standard frequencies, but you might have better luck   
   finding that frequency if you drop a significant digit or two.  It is   
   unlikely the original part was specified to 1 ppm, 100 ppm would likely   
   do the job just fine.  Didn't you say this was for a display?  It will   
   probably work fine with just five digits or even four digits of   
   frequency specified.  Is either 8.867 MHz or 8.868 MHz a common value   
   perhaps?  Really anything near 8.87 MHz should do the job.
