Can you help me identify what parts I need to replace these. The doors were installed 2005. Large panels 8X4. The screws and nuts have also been stripped so I would need those along with wheels

Thanks for contacting SWISCO.com. It is going to be difficult to positively identify those rollers while they are still in the door. I think I can make out just enough of them to suggest our product code 81-161 as a possible replacement. This includes the adjusting screw. Normally, this roller is held in place in the door frame with a pin. If yours used screws and nuts, you may want to take the old fasteners to your local Mom and Pop hardware store and have them match those up for you.
