I have a number of 4' double folding closet doors that are original to the house which was built in 1984. I am in need of replacement upper hardware (track hardware) for one of these doors. The U sectioon of track is 4' long. There is no writing on the doors or the hardware except for the two end pieces which read: ACME, imprinted inside an oval, and the number 2041. The U section is about 1" wide with the sides about 1/2" high and formed from folding over the metal to double the thickness of the side section which ends with an inward facing lip that sits about 1/8" above the inside base of the U section. I have included 3 pictures of the track I am trying to replace.
Thank you for your help with my efforts.
