That's correct for the DB4060 since the cans, coupling loops and
notch capacitors are all the same.
But it's not true for all cavities/duplexers. Some are designed to
have the notch on one side of the pass only, where a specific can is
either high pass or low pass but not the other. Actually even then
it's more a matter of the coupling loops and/or notch tuning parts
being different, not the actual cans themselves.
I can't help with the cable length question. When I had my DB4062 (6
can version) apart I marked the cables. BUT, looking at them I
thought they were all the same length. I didn't attempt to measure
them since I was afraid straightening them to do that would put
undue strain on them.
