I have a tear under construction in New Zealand and was planning on using the plastic hinge that Classic Finn had a link to a few posts back
(sorry can't find the post or link)

Other than being more difficult to install, as you have to screw it to with the hatch open it looks OK but has any one tried something similar?
I Can't get Hurrican hinge and the postage from the US is expensive. I think your post master must look like this guy


There are some pics in my album of progress and I hope to start the alloy next weekend.
