Thanks Stephen, those were the threads I found before, and it doesn't give me an affirmative answer. I guess I could try to find a Sea&Sea store in KL on my transfer day. The place in Indo is at Pulau Weh, and pretty much everything there is very basic, so I'm somewhat skeptic mail will get there in time before I leave.
Hrrm, would it not be better to get a ball adapter that fits straight into the gopro, rather then get the tripod base of the gopro?
I got this one from ebay, http://www.ebay.com/...l-/160909864010 for $11 ,and then just hook that up to any normal 1" ball. Its plastic, but works great and with just enough movement on the ball for easy adjustments (unless you lock it down by tighting it up all the way).
