The 4.08 diff upgrade has been on the for sale section from a couple different people (keep your eye out)
This is a good mod if you are looking to get more out of your gears. I think people were selling them for about $400-500 used.
I know that people that install them love the added RPMS and HP gains. (+15whp?)
Not sure how much gains, youd have to search
