?? Looking at a new LSD
Anyone know how to tell how many spline teeth are in our rear end? Not sure how to go about it, and the rear tag doesnt specify 28 or 31....
I have stock 3.55 gears, no LSD.

I could, but Id be spending another 80 dollars. I heard the only way to tell is to actually remove the housing and such and count them.....There has to be an answer.

Nooooo, any Ford mechanic would know. We have the exact same rear as all the other Ford trucks. Anyone who's ever worked on a Ford rear would know off the top of their heads.

call and ask them, they'll know.

Hmm,
Ok, i'm confused.
why do you want a 28 spline? My truck has a 31 spline in it.
Your saying that you don't know if you have either a 31 or 28??
Your saying that you can have either but you don't know which one??
Why would they make 2 different size ring/pinion's for the same model year truck for the same 3:55 rear? Ok, now I'm NOT super genius, now I'm mucho el stupido igneramus!!!!!

Yeah, same as the Stang V8's. Why, what size is yours? I was under the impression that they were all the same. oh well.
What brand of locking diff do you have and how well does it perform? Are you satisfied with it, or do you wish you got something else?

V6 Mustangs come stock with 7.5" rear ends with 3.27:1 gearing and an open differential. I installed 3:73's and an Eaton LSD. I haven't had any problems. Auburn's are nice also. The only problem is that since the Auburns are cone type clutches, they can't be rebuilt. I'm satisfied with the Eaton, only thing I wish I could redo is the gears...next time I'm going to at least 4.30's

Ah but how false you are my friend.
My brother has the same Auburn I have and he burned his clutches out due to all the drag racing he does. He called Auburn and with no questions asked, they send him a new set of clutches. He had them installed last weekend and works perfect now.

I have always heard that they could not be rebuilt.
