Sliding door roller help

Hi,

We have two large sliding doors and they don't open and close easily. We took them down and cleaned the rollers, which helped, but we think they're original to the house/doors so 20 years old. For the life of me I can't find any identifying information on the doors to know the manufacturer. I didn't think to take pictures installed but I can if that's helpful. It looks like you have several parts that are similar and might work so looking for some advice to find the right one. Thank you in advance!!

Best,
Erin
