Wald basket legs too short for cruiser -- how can I install the basket? I recently purchased a large handlebar basket, a Wald 139-WW for my cruiser, a Trek Pure. I'm having trouble installing the basket. 

Context: The basket attaches using hooks on the basket to the handlebars (no problem there), as well as using legs that from the bottom of the basket to the axle of the front wheel. The legs can attach to either fork eyelets or one can thread the quick-release through the legs, no problem there.) 

Unfortunately, the basket legs are too short, by about an inch and a half. 

The shop I purchased the basket from isn't of much help, and my LBS doesn't stock longer legs. Wald doesn't make longer legs, although they're willing to send me a second set of legs I can modify and attach to the existing legs -- if I can wait until they can send them out in two weeks. 

I'm a little leery of attaching the basket legs to, say, P-clamps on the fork. Stability and strength are important here. Has anyone here attached a similar basket to a cruiser? Can anyone think of a way out of this, or should I give up and return the basket?
I've seen both P-clamps (a.k.a. brace clamps) and the similar, ratcheting versions used. This is actually the preferred method for some front racks on bicycles without rack braze-ons on the fork. As long as they're the right diameter, and there's a little rubber (even an old tube) between the fork and the clamp, it should work fine.
