I don't use the doorhinges!
I use the inner tube of a bicycle too make my one doorhinges!
This is very flexible and strong! Install it before you cut out the doors out of the fuse!
I perforate the inner tube at the place i want too glue it, so the glue ( epoxy) stitch good too fuse and rubber!
I saw this years ago on a german Lavi at a jet meeting. Since then i'am doing it also! And it works great!
And always use Strips of aluminium or wood too line up the edges!

Good luck!
