Bifold pin caps don't fit track

I received my order and am having some trouble I hope you can advise me on. The parts fit the doors but the plastic caps don't fit inside the rails. We measured the diameter of the caps so I felt confident that this order would work, but it's not. I've attached a few photos showing the difference. The old caps are just shy of 7/16" (due to long wear) and the new caps are actually almost 1/2" (slightly more than 7/16") as you can see. What is the solution, different caps or buy and install new rails?4). I purchased 21-066 , Bifold Door Top Pivot and Guide Pin, Cromwell and

It actually looks like you have an old Benchmark door that uses 21-044 guide pins. If you want, you can just buy the 21-100 caps and switch them onto the pins you already have. How's that sound?

Thank you Paul. Just ordered the 21-100 caps. You guys are a life saver! These doors in our house are a custom floor-ceiling size so replacing the whole doors is a bigger project than we wanted to take on. Thank you for still selling the replacement hardware and having such fantastic customer support!
