Poptop hinges

[Stesaw]

I've been meaning to ask folk that have poptop leisuredrive conversions and how your hinges are on your roof. Mine are riveted to the roof plus they have a rivet that goes through the gutter as well.. which is making four nice rusty holes in my gutters.

Are they all like that if so have people installed different hinges that aren't gonna bork your gutters?
