Alrighty, I actually have a question! 
My cat currently has a 3.00 open pig in the rear end (yeah, yeah, I'm just getting around to the rear end of the car)...
I need to switch it to a posi unit. What I wanna know is if I can just pick up a late 60's early 70's 9" posi pig and shove 'er in there with no problems (Provided the spline count matches)...
The other option I guess would be to replace the spiders with a Powertrax unit?
Comments? Opinions? Free posi rear-ends?
