anyone looking for an IRS rear end?

the guy that is building my motor is building a race car out of an early 90's nissan 300 zx. pushing close to 1500 horsepower he cannot run the stock irs. so he's looking to get rid of everything that has to do with the irs rear end. everything works good there is nothing wrong with the rear end and it comes with everything. craddle, rotors, brakes, shocks, etc. he's asking 500 for it and he is also willing to ship it anywhere as long as you pay for it. he owns his own engine shop so he gets a fat discount on shipping which he is happy to use for the shipping of this rear end. let me know if anyone is interested. i can get pictures if need be.
