Jerry,
I'm a litte ashamed to admit, but I used common household door hinges you can get from any hardware store -- made by Stanley. They are like two bucks each, or some equivalent of free. Look at what you bathroom door swings on, that's what you are after. I used two 3-1/2" hinges per door.
However, I did modify them. I hammered the ferruls tighter against the pin (to remove slop) and spot welded the ferruls so they won't open up (and cause slop). I also bent one of the hinge flanges a little (next to the hinge) so it would tuck in a little tighter in the resricted space available.
The hinges are cheap enough to experiment with.
It takes quite a bit of fiddling and probably some fiberglass carving, but the doors can fit and hinge nicely. In my case, I can open my doors almost 90 degrees before the leading edge of the door wants to hit the body. My door stops are adjusted to prevent that from actually happening.
Have fun.
Mark
