I am looking for 250 units of this window roller.

Very similar to your 87-163 but a width of 5/16 53524

I agree, our 87-163 looks very similar to your roller housing. However, the width of the ales are .388" instead of .340". Could you still get them to work? Perhaps you could grind our axles down slightly, if necessary.
