Finally busted the rear. What now? Ok so i finall broke my rear end. i want to replace it with something strong as hell so i dont have to worry about it. do you recommend getting a 12 bolt? what gears? I want to have the car fast as **** and still streetable. not just a track car. how will my top speed be effected by huge gears because im thinkin of throwing 4.10s in it. I know its gonna hurt gas on the highway but i dont really care. Im not driving it everyday. where should i buy a rear? Im thinking of going with a Moser 12 bolt. id prefer to stay away from the ford 9 inch. Should i get it new or used? Also, is it a direct bolt in or would i need to modify to get the 12 bolt in?

Moser 9 inch
Put a 12 bolt into a early Chevelle, Nova, Camaro, etc and you can beat the crap out of it, and not hurt anything. Put one into one of our cars with a torque arm, make a couple 4000 to 5000 dragstrip launches, and I can just about guarantee you'll pick up gear noise. If it is a drag only car, you'll never know or care about the gear noise. Drive your car home from the track, and the noise will drive you nuts. I feel the torque arm stresses the 12 bolt housing, causing distortion. We have never seen this happen with the 9 inch housing.
Exotic Performance Plus strongly recommends the Moser nine inch. This rear is even tougher than the Moser 12 bolt, and the horsepower of the late model F Body cars keeps escalating every year, which requires a very strong rear. With the recent introduction of the 6.2L GM aluminum block and the excellent flowing 6.2 litre heads, the horsepower of these cars is going to just keep climbing at a very fast pace.The nine inch will handle the power, plus we prefer the way the torque arm is bolted to the nine inch in the same way the oem rear-end is attached. (This is the only good thing about the stock 10 bolt...) The Moser 12 bolt uses four short bolts to attach the torque arm, and they have a habit of loosening up, even when loc-tite is used. Why the nine inch is stronger than the 12 bolt. The 9-inch has an internal rear-pinion support that also supports the gear end of the pinion to limit gear deflection under high torque loads. This seems to be the major reason why the 9 inch doesn't start whining after high rpm clutch dumps, when the 12 bolt will pick up noise.The 9-inch locates its pinion gear lower on the ring gear to improve tooth contact, than the 12 bolt does.The 9-inch has a 0.125-inch larger ring-gear diameter and internal pinion support than the 12 bolt does. This is not much of a difference, but it is worth noting.
If you are really worried about weight, the Moser M9 fabricated rear is the same weight as the 10 bolt you have now. Here is a link to it. http://www.exoticperformanceplus.com...html?item=1324
Here is a link to my Z28 which got the very first f body M9 rear.

In my opinion the S60 is by far the strongest thing out there. I'm starting to notice alot of the big turbo guys using narrowed S60s. That's why I got one, but they are heavy as sin. They actually have less drivetrain loss than a 9" suprisingly, and is a direct bolt in (no bullshit) other than needing a new driveshaft.

+185696232415 for Midwest Chassis,,,Eric has great products and great customer service to boot..
going 9 inch may be excessive for your needs, but thats up to you and the person you deal with on what your needs actually are or will be.
Good luck and give Eric a call,,,his customer service is above and beyond anyone i dealt with when i did my rear end project. I bought a used rear end locally,, and he STILL went the extra mile to help me out.
