All the AU BB AI parts should be at RFSHQ.com (I think).
You need Megabyte's pack, RFS's hydraulics, HackerX's AU crack pack, ][cer's pack, Snow Burst's plow (which I think comes in the zip), and DarkRat's red and black extenders (which I think are in his second pack).
The new Snow Burst I don't think will be up for dl, I don't think it's quite as fun to play with as the old one, that's just my opinion...also with DSL coming out, I don't want to make something that no one will want to use.
Now if everyone says "yeah yeah release it!!" (which I doubt will happen), I will.
Here's a pic of Snow Burst1 that I dug up from the merky depths of my comp.
EDIT: Does anyone here have Snow Burst and had it work?
