Found this while surfing could be a useful alternative to rebuilding your rear!

[blackbeast12]

I was surfing the web tonight and i found complete rear ends, brand new with 4:10's. We all know ford racing sells 3:55's and 3:73's but not 4:10's. This a great price, so i just wanted to share it with my svt brethren, enjoy:
