I contacted Art's today. My parts are on the way here and for less than I have found anywhere else. Thanks for the tip.
In my search for parts I found a guy in Alabama that is parting out over 60 4 wheelers of different brands. If anyone wants his number send me a pm and I'll send it to you.
Zukifreak, do you have any of these bumpers (pics attached) I'm after 1 - 2 of them.. Also need an oil filler cap, and a brake cable (the one from the foot pedal to the rear drum). I live in BC, Canada, but I have a shipping depot address I can receive shipments from in Point Roberts, WA, just across the border from me (30 min drive - 30 min border crossing - each way).
Zukifreak hasn't been active on the Forum since 07-15-2015. Somehow i doubt you'll get a reply from him regarding what your looking for. But hey, maybe you'll get lucky. Just thought I'd give you a heads up.
If you don't mind having it shipped, you can use google to search kijiji across all of Canada... try entering this into google:
site:kijiji.ca king quad 300 bumper
You can then click on the "images" tab to quickly scroll through and scan what you are looking for. You can also apply filters like "within last week" or "within last month" so you are not looking through super-old ads.
Good luck, I'll keep my eyes open for ya!
EDIT - just posted this in the other thread... here's one for sale right now (although he said he won't ship :/ )
