Need replacement for sliding patio glass door

I think it is close to the 81-286, however the dimensions of the 81-286 are not the same as the part I have. I have looked through all the single wheel patio rollers and do not find any others that are like this. Am I missing anything? What are your suggestions?? Is there any way that I could just replace the wheel and use the old bracket??

The length of my part is 2 6/16 " long. I do not think this is significant as there is room for longer and shorter in the rail. The height is 1 1/8" which has to be spot on because it fits inside the bottom rail. The length from the top to the tab on the side is 17/32" . There are cut outs on the side of the rail which the tabs slide into and lock the roller bracket into place. This is important in order to line up with the cutouts. The width of the bracket is 21/32" with the widest part containing the tabs to be 3/4". The wheel diameter is 1 1/4".

Hope this will help you. I have no success in getting through on your phone line. Thank you so much for your help.

What do you think about using the old bracket and you guys supplied me with some new metal wheels. I could use a drill press to drill out the centers of the old rollers and then use some new rivets to install the new rollers
