Yes.. I think its cheaper to use PowerHouse's rear-end setup..
Moser 28 Spline axles, $389
FMS Traction-Lok $229.95
Total=$618
Half the cost of that setup.. With the other $532 bucks, you can put it towards a Zex Nitro System.. Then you'll be kickin azz and taken names Brodude2002!
But overall, they are still nice finds, and you did the right thing posting them..
