get yourself a 60/9 housing from diamond. $1250 for Cs and housing doesnt seem that bad. the chunk will be a little pricy but after that, you have a light weight, bomb proof setup. i want to do that in the future because like you, the only thing left of my axle that i will want to upgrade is the housing. the front of mine is getting really cupped too. the very bottom bolt is getting pretty shaved.
