Thanks for the responses,

I think I will go with the 4.11 front and rear. What manufacture of gears is the best and what manufacture should I stay away from?

Ive never installed gears before but I pickup on things pretty quick and I have my service manuals that I purchased when I changed out my 258 engine for the 4.0. Is this something I could do myself or should I take it in and have them installed?

Thanks again for the excellent feed back.
