Pierce dropped off his sweet supercharged cruiser for some 4.88 gears last weekend. Everything went nice and smooth. If anyone wants a detailed thread about gear installs, check out my other thread here.
The only thing I did not like particularly about the Nitro front kit was that you have to use the supplied flange because of the thicker pinion splines.
This requires a non-Toyota seal but the one supplied seems to be of a good quality so it's really not that big of a deal. One other issue is that the outer oil slinger has to be flared to get it over the thicker pinion.
