Renin Bi-fold mirror closet door 36x80 opening

Hi

I am looking for the bottom right side (looking at mirror side) pivot pin for this Renin 36 in X 80 in mirror bifold door. They were removed for a mold remediation and contractor lost the bottom right pivot pin. I would like to purchase the bottom right side pin and roller that goes in floor track and perhaps an extra top pivot pin. Thanks for your help.

Al
