Hey, Charles. We only carry two rollers that are similar to yours: the 23-154 and 23-155. I'm just not sure of the wheel size you need, or the exact off set on the bracket. The 23-155 has a 1/2" off set, but looking at your photos your back set on the one roller could be larger. If these rollers don't match up to your I would suggest ordering a new track kit like the 23-500 for a 4' wide closet or a wider kit.
