Question:

Hello, I have Thule aeroblade roof racks and a Thule summit box. What mounts do I need to make this work?

The correct mounting hardware for your Thule 631 Summit Roof Cargo Box would be the # TH04997 kit you'd looked at. This is a slightly different kit that what was originally used, but because the box was discontinued in late 2001, they don't offer the original mounts anymore. Thule assures me that the # TH04997 will work. I'll provide a diagram that will give you an idea of how the mounts and the box go together. These mounts are compatible with crossbars that are less than 3-11/16 inches wide, like your AeroBlades.

I've linked to a product description video showing what's included with the mount kit.
