Why do people sink ungodly amounts of money into their motors sometims transmissions but want to get used stuff or ask what's the cheapest way to build a rear end. Seriously.....WHY??? blown, stroked, nitrous..... is what they have. 8" rears with ez lockers is what they have. ez lockers are crap 8" rears are crap. Time and time again as I sit at my friends differential shop I see at least 4 people a day come and ask if he has used parts or whats the cheapest thing to do in order to have a posi. Then when you ask them what they have oh camaro,mustang, etc with an aluminum headed motor that they spent 5K on or more, but here they are complaining about spending $400 on a posi unit. Damn cheap skates!! So why do people skimp out?
