Having trouble installing my 81-128 roller

Question

Am trying to install Anderson roller 81-128 purchased from you. This is a 96 x 80 in unit , each door 77 x 48".

Have been able to remove outer slider but inner slider does not want to go up and over the slider rub for the outer door. Have adjusted old rollers to recess inside old door. What am I doing wrong?

The slider rib for the outer door had two screws, which I removed. The plastic plate looks like it comes up, but does not want to come up. I don't want to break it by forcing.

The unit was installed in 2000. Seems to be an Anderson unit made in Canada

Have opened the door and found unit attached. Can you match it?

6" long, labeled "TRUTH". 31761A

I have two 81-128 which I will need to return from previous order

Hope you can help

Thanks for contacting us, Don. If your door is a wooden patio door like Andersen patio doors often are, then the sliding panel comes out of the frame from the inside. The Andersen wood door is held in place with the top header screw on the trim. Take a look at the top inside of your patio door track to see if there are screws holding in that top trim. If there is, you will need to remove the trim and the door should drop out at the top inward toward you. Let me know if that works!
