Need a mode knob for my 2001 GP GT

Hey all,http://i170.photobucket.com/albums/u251/LH6261966/ModeKnob.jpg

I recently turned the mode knob in my car and noticed it easily spun round in my hand. I pulled my hand away and the knob came with it. It is definitely broken and need a replacement but can't seem to find a place online to purchase one. I could probably get a brand new one from the dealership but would appreciate finding one used that will probably be cheaper, or is it? Anything you guys know?

Thanks,

Lou

I got mine at Autozone. They sell a 3 pack for GM's, one of them should match yours. Made me feel kinda guilty as I just thru the other 2 away.

Autozone huh? I'll check into it. Thanks for the tip.
