Revos, lews and some BP reels

I know it can't be just me but I noticed that a lot of parts between these reels interchange. I think, not sure but aren't they made in Korea. Is it possible the same plant. I use Revo pawls in lews all the time.
Heck I was playing around and I put a Revo S side cover on a Lews Speed Spool and everything lined up. I even casted it. Braking is different but it still cast.

A lot of the parts are made in the same factories but to different specifications and metalergies.
