Oceanic bulkhead size?

[supernovabjt]

Im in the process of replacing the stand for my oceanic 58 rr and I would like to upgrade the barbed bulkheads to threaded ones. Does anyone know what size hole oceanic drills in the 58rr (megaflow)?

Thanks tropills. Where is a good place to get bulkheads, I was looking at glass-holes but they seem a little pricy ($7.00 each)?

check the BIG auction site. I just bought 12 of them for 19.99 shipped.
