horizontal sliding window tandem rollers

Hello,
The dimensions of the window slider tandem rollers in the attached images are:
Overall housing height = 0.30"
Overall housing length = 1.52"
Width of housing body = 0.55" (width of housing across the retaining tabs = 0.62")
Housing appears to be nylon material. The housing has one protruding round feature that fits into an 1/8" hole in the bottom of the window frame (to retain the roller and keep it in position as the window slides open or closed)
Roller diameter = 0.30", roller width = 0.24"
Roller material is steel (it's magnetic and it rusts)
I am not sure who is the maker of these windows. There is no logo or tag I can find on the window or on the window frame.
The approximate year of manufacture for these windows is 1996 (I bought the house new in 1996)
Your part number 87-181 is the closest match that I can see, but maybe you know of something better as a replacement. I can send more images if that will help. Thank You!

Hi Casey,
OK, see if these 4 newly uploaded pictures better show the roller housing assembly details. Thank you.

I did have a glass technician at my house today to estimate cost on replacing a cracked glass pane in a window. I asked him if he could recognize who the manufacturer of these windows might be. He said it is possible that they are Jeld-Wen windows, based on that there are alot of houses in my area that were built with Jeld-Wen windows (though he wasn't 100% certain).
