Matt's 95 Stang

I will say that I have yet to have any problems with my posi and gears after about 2 years. I did what Neo is suggesting and picked up a used 7.5 (you can use any 7.5 from 1994-2004) and rebuilt it at my leasure (but I had someone install the gears and posi as I didnt have the knowledge or tools) and reinstalled it myself. You can install yourself alone with a set of jack stands and 1-2 jacks and basic tools.

That's what I'm planning on doing, but where are you finding a used 7.5 t-lol? I can only find new ones?

I actually just found this one, I think it looks really good.

The only question I have is, will I have to change anything with the axles or will everything line up correctly since its a 28 spline?

you dont want to get a used one. You have no idea what its gone thru. It cost almost as much for a rebuild kit as it does for a new posi unit and will cost you even more to have someone else rebuild it.

Ya that's what I figured.

So I was looking at the trutracs and I was wondering how you get a specific gear ratio in them? Do you just pick which ratio you want when you buy it or is there a set of gears you have to buy like on the ford T-lok?

your ratios are set by a ring and pinion gear that gets bolted to the differential. As long as you get a 7.5" ring gear (hence the name of the 7.5 rear end for the car) you can bolt it to any 7.5 differential. In case you aren't aware that center chunk that the axles slide into is called a differential.

Yes I knew that. The thing that was confusing me was that I was looking at videos and diagrams of the helical design and wasn't sure where it would fit in there. All the clutch type differentials look simple enough to me, I just was unsure of the trutrac one.

It's not fault Of the7.5, just the POS ffrP t lok made for the 120 hp bronco 2

^ well hell im just a little ol' single port. 120 is right in my area.

agreed, b/c of the wear pattern too. so once its in a another vehicle the wear pattern has to change again, which is horrible b/c it can whine for sure and break if the wear pattern is too warped.
