whats the cheapest way i could obtain a posi for my 86 trans am. as of now i have stock peg leg and its getting tiring of spinning one tire every time it rains / is there a kit to convert my diff to a posi unit or do i have to get a whole rear end off another car?

thanx

 

you could always call around to local salvage yards and see how much they want for one...i dont know if they make a kit or not.

 

slponline sells takeout posi carriers for less than 100 bucks. They are 28 spline 3 series units...

does that mean that they just sell u the guts of a posi and u open urs up and replace it with the one u bought from them? do i have to buy any adaptive kits to convert it?

 

No adapters in the diff. You have 26 spline axles. The cheap SLP posi requires 28 spline axles. Lots of different ways to get you more traction in the rear(limited slip/locker).... What do you plan on doing with the car, and how much do you want to spend?

 

intake , cam and maybe carb and dist is all i plan on doing to it . its my daily driver . i don need some more traction in the back tho. wht are my other options? i see that the splines are different so is it a pain to change them?

I know this is for 28 spline axles, but I just thought Ide post it. Helps with a visual of what the unit looks like, and gives an idea of what they will go for if you choose to buy one used or whatever. Just randomly found it, so I thought what the heck.

you can change your axles(for the SLP), or you can buy a posi specifically for your rear. check out www.jegs.com or www.summitracing.com

 

go to the wreakers and rip one out
