I used hidden style hinges from an iraqi army truck for mine.
I built pockets for them out of two inch square stock.
Mid to '66 ford f150 pu's had very similiar hinges.
They even have bolt in pockets, if you can find one in a junkyard, get the pockets and just weld 'em in. Then you can unbolt your doors easily.
As far as latches go, i wouldn't suggest anything but the bearclaw setup.
I used the mini hinges that the have, as the size of the regular setup is too big for the bug doors.
I also went for thier install kit
, was a great setup went in smooth and clean.
The first pic (link) is the third time round doing my doors. Take note of the location of the hinges. The first go 'round I used an old Hot VW's article on doing suicides with the OG stock hinges, and a set of early bus latches. I tried it, didn't like it at all as th stock hinges flexed alot for some reason.
There's a guy with a pink bug come to the classic all the time. His is done with stock hinges, and if you walk up to it, you can see the paint cracked on them from ten feet away.
The second go round was with the iraqi hinges, but in the "stock" location on the rear door post. Worked great up until I tried to open my doors. They would open up to about halfway before the center of the door hit the rear quarter panel in the middle of the arc on the side of the body... no good.
So the third time round, moved the hinges in farther toward the center of the arc, and bingo.... perfect clearance. My doors open just slightly farther than ninety degrees from the car. And, the hinge pockets create their own door stops.
Hope this gives you some ideas...
I have some more in progress pics, shot me a PM with an email addy if'n ya want 'em.!
