2.5"+4" lowering kit on a longbox 86

[Franko]

This is one of my winter projects, install a lowering kit on my 86 GMC. Where can I get a kit? What kind of kit should I get?

 I live about 45 minutes from the Windsor/Detroit border and can pick the parts up.
thanks

I recommend getting a spindle/hanger/shackle for that setup. 
I can get you a 2.5/4 kit for your truck for $445.99 + shipping, but you would have to give me a place to ship it to in the US.
