Replacement parts for 1993 sliding glass door

I am looking for placement rollers and top guides. My house was built in 1993 and the sliding glass door is original. 
For the roller assembly: 
H: 1 9/16"      W: 7/8".   L: 2 1/4 "     Wheel diameter: 1 1/4"
For the top guide: Wheel diameter: 1 1/4"
I bought assembly rollers from home depot that did not have a wide enough channel to slide onto the door. That product was "Prime-Line 1-1/4 in. Steel Ball Bearing Sliding Door Roller Assembly, Peachtree Citation Doors"
I believe the parts I need are Product Codes 84-082 and 81-112, but I want to be sure that the width of the channel is correct first.
Thanks!
 
 

Thanks Bob!
