Too late to change now Daniel, just finished putting your 9" together with the Detroit today.
Everyone's gonna die sometime!
But as far as drivability, Icy roads and Detroits can be scary, you wouldn't want to goose it on a curvy icy road, or shift a manual without being careful on an icy curve, or use your gears too much to slow you down on an icy hill.
On a slick off camber hill or loose soil side hill the rear end may tend to slide downhill.
Also long sandy hills going down, the rear end tends to want to float.
But i've been all those places and haven't died.....yet, just have to be aware and more careful.
ARB or OX eliminates all those problems, but at a considerable price!
Mine with the 5 speed is alot more noticable then it was in my other rig with the automatic, I feel it tug to the left when shifting, sometimes a loud pop after making a turn in gear. Lot's of bangs and pops in parking lots.
