In a 3rd gen.?My posi unit blew out and a friend suggested installing a OEM diff. instead of an aftermarket unit.

i got mine from SLP for $85, definately worth the money. Probably good for up to 350HP

 

Yup, a direct bolt-in; except that since you have a 88-back car (unlike the guy with the 90) you have 26 spline axles, where the 98-02 posi uses 28 spline axles like the 90-up 3rd gens do. So you'd need a set of axles to use one of those.

 

yup....wont be able to use it unless you get some 28 spline axles.

 

thanks for the info but saw that on SLP's site.

Bill, I did that very mod in the spring of 1999.

just a tid nit of info. I don't know if they fixed this yet but SLP has been out of those T/O for months. something like 6 months or so. if you get the heavy duty one then you'll have no problem but for 499 thats out of my league. I went on ebay and got a almost brand new t/o for around 200 with gears. 3.73 gears. well hope this helps you a bit.

Well I ordered the Zexel-Torsen from SLP.Told me that they just shipped 350 and should ship mine in about a week.

They were out of some one of the pieces that you need to install it, not the diffs themselves.... but it won't be long before they do run out; and when they do, it's final. Bummer. Get it quick if you want it.
