Missing a top pin and wheel part

A home owner from Cherry Hill, NJ says:
Hi, I've had someone helping me reinstall heavy bifold closet doors that are original to the house built in 1965. We are missing the wheel and pin from 2 separate doors. The ones I ordered are not the right fit. My installer helper says they seem to be too long to fit. Photos are of the correct parts on the matching half if the door. Thanks for your help.

Thanks for posting. Would the 23-124 or 23-126 be a better match? If not, can you remove the rollers and give us dimensions? Many thanks.
