I tried the 87-036 in the past and it didnt work. Would you be able to send me one to check the fit with the new style? I'm going to need 16 of them so I don't want to order the wrong size..
Thanks

Hey Phol. I am afraid we might not have an exact match for this window roller. The 87-221 comes to mind, but it looks different enough to give me pause. Window rollers do need to be exact in dimensions to be a working replacement. Take a look and let me know what you think.
