Are you getting tired? You seem to be missing a 9 this time. I think this time the numbers you meant to type were something like:
crystal across cap: 3.57960
target: 3.579545
without a cap: 3.57966

If that's right, the cap is pulling it 60 Hz, which is a nice amount of pull, so it seems something else is wrong. Which capacitors in the reactance tube section and the 3.58 MHz oscillator have you NOT replaced? Do you know for sure the reactance tube is good? Is the plate voltage 5 volts lower than the B+ supply as the schematic says? Time to look for anything that is not right.
