Bypass Top Roller Assy for mirrored closet door

A handy person from North Carolina says:
I need to replace the bottom track which I have identified as the 23-242 72" Sliding Mirror Door Bottom Track. The doors have the 23-215 Bottom Guide Assy installed. I would like to replace all the door hardware, but have been unable to identify on your site the Bypass Top Roller Assy that specifically matches those currently installed. The closest I have been able to come is the 23-196, but I would like clarification that it is a suitable replacement part. Please see the submitted picture. the roller is convex. The only identifying number is DSH 20121 that also appears on the bottom guide assy bracket. At this point, I can only assume that it is the part number for the bracket, but not the entire assembly.

I think our 23-027 is a closer match. Look it over and see if you agree.
