Question:
I bought a used xcargo with a white top and grey bottom with a snail on it. It did not come with the u locks to mount it on my pilot luggage rack. I can not find the model number anywhere so I can order the correct parts. Please help!

Expert Reply:
The Sears XCargo rooftop carriers were made by Thule and so you can use the Thule u-bolt type kit # TH05603.
We also offer locks and keys for cargo boxes like your X-Cargo in case you ever need either of these items.
A lot of people that use rooftop cargo carriers also select a step like # TE97FR. This folding step is lightweight aluminum, it comes fully-assembled and it gives you almost a foot of extra reach for loading and unloading your rooftop cargo items.

Hi! I also got one of these. I have Yakima Roundbars on my roof and the spacing doesn’t line up right — they’re too wide apart to sit perfectly under the box. Will this same Thule kit work, or is there a better option? I assume I’ll have to drill holes through the bottom of the box, right?
