Hey there! I recommend you take a look at the 23-270, 23-271, and 23-272 bottom tracks. These are compatible with roller assemblies with a concave wheel like yours. As for the top track, see the 23-244, 23-245, and 23-246. We can't make any promises without seeing the original track but review the specifications and see what you think. |
