The same wheel is used in both 87-072 and 87-090, making the housing the only difference between the two window rollers. Attached to this post is three alternate views of the 87-090 window roller. I do not have any indication that this roller was used by Howard Industries, but it is possible. I do not have a catalog page of Howard Industry window rollers to fax you.
Take a look at the two pictures provided in this post. I took some closer dimensions of just the wheel of the 87-090. The wheel is SWISCO part 87-089 and has a 5/8" outer diameter, 1/4" inner diameter, and a 5/16" thickness. I do not believe Howard Industries is still in business. There is no minimum order online at SWISCO.com, so you can just order one 87-089 to try out on your window.
