The hinge on a '36 is literally part of the door. You could make your own hinge out of rod and tube; but probably easier to just get another door.
I`m currently going through this for a customer. He came up with a new 37 Chev Pickup Glove Box hinge and I had to make new mounts and change the relationship of the hinge pivots to make it work. Would have been almost as quick to scratch build one.....but it worked when I was done....
