Hatch Fastener? hydraulic hatch arms?

[miamioffshore]

Well I found out the hard way that my cabin hatch's (the overhead ones that allow you to access to the deck, need new hydraulic arms, they stay open for a couple minutes and then fall down with the first gust of wind, one of my fastener broke in half when it fell. So where do I get new hydraulic arms and a fastener?
