I'm afraid it's still a little hard to tell from this photo what you have. Basically, if the wheel in your rollers have a recessed groove that enables them to slide along a raised track, then you have a concave roller, and the 23-070 or 23-086 will work for you. We're pretty sure this is what you have, but just double-check to be certain. |
