Looking for a replacement mainspring for service. I believe it is Seiko part# 401830 for Seiko Sealion Movement 8305-1010. Any good places to source these parts outside of EBay?

Well I got a beauty from these guys, thanks for the heads up. It cost me a pretty penny, but worth it to get my M77 back up and running.
