ATV Parts and Accessories

ok, i'm rebuilding my camaro with no expenses spared, i've got a 575hp small block hooked up to a tko 600 5 speed trans, i have a heidts front sub-frame, and a heidts 4 link. since i'm doing all this id hate to put a dirty old rear end in it. and what i need is a beefy rear end, complete, axles, axle housing, locker, gears and 3rd member. i'd like it to be from 3.23 to 3.73 gear. i've been looking all over for it, i've been to summit, jegs, moser, strange. also, its a 10 bolt right now, i'd prefer a 12 to get rid of the c-clips, but im not that concerned about that. if youve done something or know where i could buy a full rearend, could u send me a link?
ok, it's a bolt on 4 link, uses all the same holes and everything. right now i got it on a lift awaiting a rear end. lol, it's just sittin there without a rear axle. the better fit the better. i'd like to to be about the same size and everything as stock. but i need it to handle the power.

Car symptoms: Mostly noticeable when cold. If I am at a complete stop and slightly press the gas I hear a clunking sound coming from the front left tire. While I am driving I feel the car tires spinning (normally a quiet ride), its not noisy but it can be heard and felt. When I make turns, I'm almost certain its with left turns, I hear the same sound but more like a pop this time.

Any ideas?
Thanks in advance
