I used to work as a mechanic at a GM dealership and my parts guys ordered it from tonka 4-wheel drive in edmonton.. im sure if you call the number on the BDS website they can tell you some places to one.. its an alright kit, it has held up pretty good for me so far, only complaint is the drop plate that comes with the kit, wouldnt recomend it for any serious wheelers unless you want to punch a hole in your front diff = ) ... it was pretty cheap too.. but i think someone said at some point, "you get what you paid for".. oh yeah and it also comes with rear blocks...
