It'll probably cost you as much to find the 8.5 posi/ltd slip unit and install it here as it would for you to locate, purchase and install a posi rear locally... just be patient.
Thanks for the quick response. I know how to drop the rear end assembly but I don't got the proper tools to take it apart. Also without the track. I guess it would be easy to get a stock posi.
We have the advantage of Hawaii being a captive market (no outside sales as shipping is too high) and an overabundance of G-bodys that others cant get to.
