Hard to tell what the offset is based on these images, but look at our 23-031 and 23-047 and see if either of these can work for you.

Would a different view help you decide offset? If I measure indent on the wheel part it is 1/2 inch but both doors have the same 1/2 inch hardware. Is that unusual?

Does this picture help determine size better?

No, that's not unusual. Some manufacturers have their track set up with the same rollers for front and back doors.
