Sliding patio door parts

A quick learner from La Habra, Ca says:
I need confirmation. I have a condo in Rancho Mirage, Ca. that has three sliding doors and screens. It appears that there is a bug blocker, #59-053. The wheels have been changed many times with the wrong parts, I believe.

The project was built by Sunrise Development. Am I right in the part number? Wheels and tension rollers I got from your website as 84-101. How are the corner braces installed. I don't want to separate the corners.

2 of the doors are 96 inches and 1 is 79 inches

I would like to get the right parts.
