To post the schematic, either make a screen dump and post the image or print/export to .pdf and post that.

I was going to say exactly what tumbleweed just did so now I won't, but I'll say this:
Is it an actual oscillator (not a crystal or resonator) then you should be able to drive both PICs directly from the output of the oscillator but check the datasheet for the oscillator, I believe you can use either HS or EC mode for this.
