dunno if you seen this or not, part of the same page as part 1. anyway, this bella vista dude has a bunch of stuff on his own page. very informative. a lot of 4x4 stuff but a diff is a diff I guess, same for cooling systems and other write ups he has. it used to be on the pirate 4x4 page but that site has changed format or something so it looks different now than when I was there last. check out the tech articles if you have some time to burn off.
