My buddy has a 03 mach 1 he said he "thinks" that his 3:55s will fit in my 2012 5.0. Anyone ever heard of this?
O really? I dont want any noise issues lolPhysically the gears should fit. Changes have been to the outside of the pumpkin on the 8.8s and to the axles and diff. The gears themselves are the same. You'll have to have them set up and used gears are a major crapshoot noise-wise.
Yea im not even gonna attempt it just gonna fork out the extra cash and make sure its rightyep, here's the trick: installing the used gears the installer has to try to match the pattern up the way it was in the other car and that's hard to know with the gears on the bench. He's making his best guess as to which of the many acceptable patterns he chooses. Not saying it can't work, I just wouldn't do it on an S197, which are already pretty notorious for transmitting gear whine to the body shell.
