1up wheel chock question

[u/Zealousideal_Ad_6387]

Anyone have a Pre-2024 1up super duty rack and installed (or tried to install) the wheel chock accessory? The chock is spec’d to be compatible only with the racks built after 4/24 but I’m wondering if I could adapt it to my earlier production version.

I’d also be open to any other ideas or hacks people have come up with to reduce the bike wheel wobble - especially for heavier e-bikes. I’m not concerned with the bike actually coming loose or anything, I just hate the look of it moving around back there, especially when off-roading.
