Two different window rollers

I have 2 window that I cant identify the manufacture so I wanted to see if you have a roller assembly that would work for me. The dimension are 1 9/16 overall length. 1 3/16 center to center. It is 9/16 wide plastic holder and has 2 3/8"inch brass rollers.
The 2nd one is for a different window. The dimension is 1 3/4 length and 1/2 inch wide. it has a 1/2"brass roller. This one installs in the window veritcaly.

I am sending pictures of both roller assemblies.

please email me and let me know if have one that will work.

Hi Paul
Yes I think they will both work. I would like to buy (8) of the 87-181 and ( 12) of 87-196 if that is possible? Please let me know if we can buy in small quantity.
Thanks Dave
