Smaller Screen Door Roller

Hello, have been searching for the brown roller assembly for a patio screen door. As you can see it is smaller wheel diameter about 1/16 smaller and also the thickness of the wheel and the folded metal body is about 1/16 thinner. as you see int the photo the tail pivot is longer by nearly 1/4 inch on the part I need. I took the photo side by side with the common white nylon part that is readily available. They will not fit, the 3/8 width needs to be forced in the door opening making it inoperable. The dimensions of the brown wheel assembly I need are length 2.00 inches thickness .225
tail pivot .870 wheel dia .975 wheel thickness .235 photos show what I am saying, it would be great if you have or can get these, thank you Tony
