Question:
Hi, I have a Yakima, SkyBox 16 Carbonite Box from several years ago. My new car has wide roof rails with t-slots. Could I use the Yakima T-Slot adapters for my roof box? Thanks!

Thanks for your question, Bhavin.
I couldn't find anything definitive so I reached out to Yakima to get confirmation. They let me know that the Yakima SmarT-Slot Mounting Kit part # Y25AV will not work on the older SkyBox's. The only replacement hardwre available for the older boxes is part # Y62XR.
The mounting mechanism is different in the newer SkyBox NX so the mounting hardware wouldn't be interchangeable. Hate to say but, we don't carry anything that would allow you to mount your current box to t-slots.
