Dix Hanger (Pocket Doors) Keep or get new Hardware?

Our pocket doors have the original Dix Hanger rail and hardware. They look to be in great shape. I don’t want to replace 115 year old hardware with even the best new modern crap. These have lasted this long, why replace? One door works perfectly and the other is 90% stuck in the pocket with both sets of wheels off the track. It’s VERY stuck. Won’t budge at all so I think the back hanger is caught up in one of the suspension brackets. The Dix hanger has a secret feature that allows you to remove/install it in the middle of the length of track but only if you can move the door to align the interference fittings with sets of little holes in the track. I think I have to put a hole in the wall to get this door unstuck. Suggestions?
