so i've built several jeeps in my time with my son. if they made it i put it on. now i teamed with with a local mechanic in firestone colorado to help me customize a "04 Rubicon complete virgin. gonna stay calm for a bit, on retirement. normally i would do 35" or 37" pending suspension modifications. this time i have a 4" suspension but wanna kinda fill in the wheel well. it has stock diffs with 4:10 gears . would prefer a 34" but metric sizes differ, not really wanting/needing 35's no real manufacturer preference
