How sure are you your generator is good?
I am asking because if you used it to align other radios it will work with them then.
Do you have a counter that could confirm the accuracy of 460kHz?
Also, is it possible you simply have not found the spot in the IF cans where the signal would go through? It could be simply really badly out of IF alignment, so one of the filters would always block it.
I think now even more, it is time to disconnect the filters and align them one by one; start from 27 first, then solder it back and align the 21.
then try to inject the 460kHz via the 6A7's cap.
