2 Sliding Patio Door Wheels for my Grandma :)

Hello!

My grandmother lives in Bakersfield, CA...in a house built in the 60s. She thinks that these wheels were replaced back in the late 90s...and i can't tell if they were replaced at the same time or not. Although similar...the wheels are definately different. I have seen posts on your website showing similar wheels and need your help identifying/replacing these for her. I tried to get by with a wheel from Lowes...but it doesn't lock into place and is not proper size so its a temporary fix.

I attached a picture of "Wheel 1", which is the top wheel in the drawing i made. I only have drawings of the second wheel as it is still being used on the door but is on its last leg.

I appreciate all of your help!
