Length is 96"
Hello,
Your roller resembles the 23-081 bottom roller, which uses convex wheels.
We do offer tracks for convex wheels like the 23-240 but they are not offered in the length you're looking for. With that being said, you can use two 48" tracks and cut the second one down to size using a hacksaw like the 75-023A. Just keep in mind that modified parts can not be returned. Thanks for posting!
If the original rollers are still in good shape, there's no need to replace them. It's ultimately up to you if you'd like to replace all of the hardware to avoid frequent repairs down the line.
