Reducing or removing capacitance will almost certainly send the frequency higher, not lower, so you're probably going in the wrong direction with that. You could try fitting the missing C3, but if that works it is only masking the real cause as C3 was never fitted.

Did you actually think of just changing the crystal? I imagine you have a few old corpses lying around which you can pull one from temporarily. Fit a replacement crystal and then see if you can set the TX frequencies to be correct using CT2.
