Ok Im not a expert and I didnt do this to my doors but they came this way on my 68 and I asked a lot of question about them. The inside door strap holder on the kick panel was donated by a jeep and the door hinges are homemade lift off. he simply got a hinge rebuild kit,drilled out the hinges to the larger pin size, pressed the pin into the hinge and hrilled the middle slightly larger and pressed in a larger brass bushing he bought at a nut and bolt supply store to help the hinge move a little with ease. Then he cut the top of the hinge off and drilled a small hole in the bottom through the hinge and pin and put a small roll pin in to ensure it wont drop out even though it was pressed and fit tight. thats all he did and the home made half hinge lift off is working fine and currently used as a daily driver witha lot of door opening and closeing, yep no problems.
