Ok, it's time to go to 5.13's, I need to know if installing the ring and pinion will be much harder then installing a detroit? About 2-3 months ago I installed a detroit and it was a piece of cake. Only took around an hour or so. How much harder is installing gears on the same axle? Any special tools required? I can get it done locally for $125 an axle but I would like to at least attempt the 14 bolt to save some $$$ if I think I can do it.
