Heard great things about this kit...I had to fight with the dealer for a year and then ended up paying $690 to get my 4 whole door panels replaced (since they don't sell the individual pieces). MSRP on the panels is $2200. You can always check out my video saga on YouTube and see people's various results.
My dad's WK is experiencing the problem and I've heard nothing but good reviews about this full kit http://www.denlorstools.com/home/dt1..._handle_r.html
On a second look, that kit on eBay seems a lot more cost effective, especially if it comes with the chrome handles!
