Acorn sliding window roller

A home owner from Wilton, CT says:
I have older type sliding windows on my patio and want to replace brocken Sliding window rollers with plastic housing. The plastic housings are similar to your Product 87-099 but some dimensions are different. Do you have replacement parts/rollers with plastic housings which match my old parts? Will your product 87-099 work for my windows?
I am attaching drawing with dimensions of the old plasting housing and roller.

I think the 87-099 may work as a replacement roller.

The 87-099 Acorn Sliding Window Roller is used for series 2100, 2300 and 2300 windows.
