I think I'm the only Isuzu owner member, it's lonely out there. My question has to do with a diff gear swap. My 2007 8'' has a 3.42 ratio and an open diff. I would like 4.10 with a G80, is this possible. Any complications with this swap? What is the best source for new parts like the G80, and the gears? Is a Chevy dealer an option?
