I purchased these Brass hinges and I am using the original centers, as they work better than the brass ones I purchased. The person I purchased them from is out, so they are no longer available.
I am fitting my right door and had to add 1/2" of fiberglass to the rear of the door and 3/8" to the front of the door to fit the opening. As you can see, this door has a lot of patching to make it solid. I am almost done fitting the door before going on to the left door.
I hope you will be able to find some good hinges, I know what it is like to need parts!!!
