Need roller replacements please!

Question

I'm having trouble identifying this roller. The house was built in 1987 and the windows are original. Any help would be appreciated.

These sliding window rollers can be very tricky to replace, since the new ones have to be exact in dimension. The 87-020 or 87-153 come to mind as our closest options, but I have doubts either match. Take a look and see what you think.
