Strat here.

It will tell you how to find it your self.

There is a metal tag on the rear differential cover. It will say what it is for sure. It will say something like 3LS55 which is Limited slip 3.55 or 3LS73 which is 3.73 limited slip gears

I would guess that you have 3.55

 

Well seeing as you have a 4.6L you have 8.8" rear and a 8.8" IFS reverse cut front diff.

 

Ratio is on the door jamb sticker. My 3.55 LS is code H9.

 

Thanks guys,gonna order 4.10's first thing next month any good brands you guys suggest? i am thinking of motive gears since my brother uses them in his 06 mustang with no problems
