Metal bifold door, need dia 3/16 top & bottom pivots

A quick learner from Calgary, Canada says:
I bought a 48" long, 1"x1/2" low profile track similar to 21-453.
It has top slide guides similar to 23-130 that can probably work, they fit a 1/4" dia pin though.
My trouble is the pivot pins have tips that are 3/16" dia x 3/8" long.
They are plain metal without nylon tip. I need a top pivot to fit in the low profile track, and a bottom pivot to mount inside the closet opening.
Do I need to replace the pins? My former system was high profile tracks top & bottom but I cannot use bottom tracks any more.
Thank you!
Kevin

Thanks for posting. The track you show in your first picture looks like it's meant for wood folding doors, not the metal bifold doors you have now. Did you keep your old tracks? If so, I recommend using the old top track and, for the bottom, cut the old bottom track where the 21-201 pivot is located, for the bottom pivot. Your metal bifold door wasn't made to float without a bottom track, but this might work.
