360 balancer question
Replacing you balancer/damper with another one that's externally balanced should be close enough to not cause any problems. OEM tolerances weren't that close, but work ok.
Were you looking for a new/used OEM replacement or aftermarket?
I guess this is the original version 360, not the Magnum style?
I've been using Pioneer SFI neutral balancers on my internally balanced 360's. Nice unit made in Australia. I don't know where their OEM replacements are made.
