Need help with odd patio door

Hi my problem is I own a condo, and the previous owners
Replaced the wheels with the wrong wheel kits and one broke off and the other was bent.

I can see the system was suppose to have a screw going up the middle of wheel kit, so far, I cannot locate the correct replacement, wondering if you can help me identify if I DO NOT have any wheels at all.

Thanks Dave

this an aluminum door 8 foot total width the slider is 4' wide. Thanks

PS enclosing pictures as I noticed the tracks under my door are curved to hold the felt

This door uses the 81-084 without the top tabs.
Just use tin snips to cut them flush with the rest of the roller. You can see the spot where the assembly rubbed the top of the rail.
