1997 Tbird sport rear questions

1st question: What info on my door sill tag will tell me if I have a trackloc or an open rear in my car?

2nd question: Is my car an independant rear suspension? Does that mean it is set up in the back like a front wheel drive?

3rd question: I was told if it was an open rear I would have to swap carriers. How much do the trackloc (both wheels) carriers generally go for on the used market?


Thanks folks!

Thanks for the quick reply! Damn that was fast! Ok,

1: Is the code on the rear end or the door sill?
2: Gotcha
3: Each? Are there two separate carriers in and independant rear end?

its on the door sill AND on a aluminum tag on one of the diff bolts.
There is one carrier (pumpkin) per car. I have two cars, so I needed two tracloc diffs.

The label sit in the rear of the door opening under the lock. In the end of the label there are some letter witch says TAPE R S AX TR. Under the AX will you find what type of axel you have. On my -94 T-Bird it says Y, which means that it is a conventional with 3.08

Thanks, I have a conventional rear end on the car. What parts are involved in getting to a real track loc rear end? How many splines? I will assist a mechanic friend in the install. I need all the specifics. W5 is the code

W5 is a 3.27 open rear end, I had the same in mine from the factory. As far as parts all you need is a trac lock IRS specific differential, and drop it in. Simplest swap you can do to get trac loc is find a SC in the boneyard and snag the pumpkin. Its a direct bolt in swap. Next best thing to do is come up with the IRS trac lock, a Mark 8 aluminum pumpkin and whatever gears you want and have the whole thing assembled fresh, and then its still a direct bolt in swap. Just an FYI, the Explorer IRS or any straight axle trac lock wont work for vairous reason without modification. Yes they can be made to work, but they need extra work. Your best friend is an SC in the yard and/or a Mark 8, even though the Mark 8 got 3.07 open rears, they had the good aluminum pumpkin, or find a 99-01 Cobra rear as they had the 3.55 aluminum 28 spline trac loc rear that bolts right in as well.

Ban low performance driver's, not high performance cars.

It'd be a lot easier and cheaper to just buy a used traction lok pumpkin and swap yours out. Unless you feel the need to have a completely rebuilt unit in your car, used ones are usually in very good condition.
