Hey Steve, you wouldn't happen to have that posi still, would you? if you do, would it work in my 89 Iroc(26 spline axles) if I got axles from a newer Third gen(28 spline axles)? would the axles fit correctly? if you don't have it still, could you keep a look out for one? Thanks

 

I still have it. To the best of my knowledge if you managed to find a 28 spline it should work just fine. I can let you use it again and if it doesn't work I'll take it back again.
