Interesting. In their gallery they have a red WBH shown. I did notice in their package options, they show a 4.10 rear end as a $1,200 option. And to think you could get it for free from the factory.
Wouldn't be too bad to get a base stock WBH with a 4.10 already in it and tack on a number of their options, the price wouldn't be bad at all. The rebates almost cover the supercharger.
