sliding window roller

Question

On the left is Swisco part # 87-213. Now I'm trying to find the 2nd roller on the right(brown plastic) that doesn't have the large end piece for holding the whole carriage in place. any ideas? I don't need it to be brown, any color will do.

thanks,
chris

I agree, the 87-213 looks like your best match. To me, it looks like they cut off the flange to add an additional wheel to the window.
