Hey guys. I recently purchased a Wald 198 Front Basket for my bike and attempted to install it. The basket itself attached to my handlebars just fine, however, I can't seem to get the legs to attach to my front axle correctly. The legs are meant to attach the basket to the front wheel axle so that the basket does not droop when I place items inside of it.

For reference, my bike is a TREK RST CTCOM105. It's over a decade old at this point, so I wouldn't be surprised if the bike itself is an issue. This bike came with a quick release axle, but I replaced it with a new axle with a hex key lock about a year ago.

Here are some pics of my bike explaining the issue. I can't actually post a full URL yet as this is my first post, so bear with me here:

Did I install the legs incorrectly, or do I just need a new axle that's compatible with this setup?
