Moog Source Octave Switch Replacements

Hello everyone!
Does anyone have any leads on any modern replacement parts/switches for the “0” & “+1” octave buttons, on the Moog Source? The internal “spring metal” that makes physical contact has finally corroded, and broken. I have searched the forums (& internet) the best I could… and have found no information, except for replacing them with another original part, from another unit. I have DIY soldered in modern replacement tactile switches (ones that are for Roland TR-606 & TB-303s)… which have a nice “click” feel to them… and may just have to carefully glue the original blue button caps to them. But… I’m an “originalist”… and am looking for actual as-close-to OEM-as-possible replacement parts. And… “gluing things to other things”… goes against my “originalist” OCD… (as I stare at the mounds of glue used to attach the original woodwork, to the aluminum casing of the original Source…!). Anyways… any additional assistance, or information, would be greatly appreciated!!!

Thanks,
-Brian
