Need rollers for sliding glass door ASAP

A home owner from Tampa, FL says:
Current rollers have broken and I can't find any replacements in any store. Center piece that holds wheel in housing has broken off. Need new hardware ASAP. Current hardware measures 13/16" thick and 1 1/2 inches tall. I have taken pics with measuring tape, but would exceed quantity allowed for attachments. Roller wheel is metal and existing hardware only has 1 wheel. Existing hardware does not contain any markings or writing. I have attached pics from different angles. Feel free to email back if additional information is needed.

I need at very least 4 of them, but willing to buy 8 or 12.
