Replacing that one section of the band switch makes sense. Just make sure the two have the same connections, though I can't imagine they don't match.

I have a 620 I'm working on and a 630 I got for parts. I noticed that the 2 band switches differed a bit in that one or the other has spare lugs (not connected via the switch) that were used for to connect stuff. 620 had a bad BC band antenna coil which I replaced with the one from the 630.

Otherwise, the two radio's (630/620) schematics look identical with the exception of the 620 having a 10K resistor where the 630 has a shadow meter.
Can't think of anything witty.
