Thinking about replacing my 30 up front and would like to go full width. Problem is i'm pretty happy with my 8.8 and would hate to spend the money to build a new rear too. Do you think it would be pretty easy to just retube and get new shafts. i think some fullsize ford 8.8's were at about 63 1/2 wms to wms. could i get some parts from one of these? if so, what truck would it mostly likely be found on? any ideas?
