Acme bifold door wheels

A contractor from Ashley fall MA says:
We are changing a 2 door 3 panel bifold into 3 door 2 panel bifold.
I'd like to leave the existing track. I need to purchase a set wheels and top mounting bracket. The wheels have 4 wheels. The hinges say Acme. The doors were hung 1986 or so. The size of the track is about 1 7/8" wide 1 1/8 high
Photos will be sent separately
Thanks for your help

I am afraid Acme has been out of business for quite some time now. We do offer a similar four wheel trolley that may work on your track. The wheels measure 7/8" in diameter. We'd like for you to remove one of your trolley sets and carefully compare your measurements to our 23-193
