Beefy Rear End Build Up

Alright you crazy people. The Question is that i want to build a rear end that will go under my 69 cuda that will be near bullet proof and money is not a issue but i would like to keep the thing under $3K. My current thoughts are to use the new Detroit Locker Limited Slip with Moser big bolt pattern axels, a new mopar preformace 8 3/4 third member case, I am thinking a set of moser 3.55 or 3.91 gears, unsure if i should just reuse the old axel housing or get a new one. What your guys opinions on this build, i would like to only have to really build it once, and be able to take alot of abuse and horsepower.

Later the crazy cheesehead going all out.
