Thanks for the replies - any suggestions where to buy from? Should I stay with the stock axles?

Anyone have any advice on what products I should look at for converting my rear end to posi and going from 2.73 to 3.42 rear gears? I've got a rebuilt TH350 and a very strong 400 small block in a '70 Monte. I don't drive the car that often, but I live out in the boonies, so when I do it's usually a 100 mile round trip or more. Any advice would be appreciated, and I'm sure there are members on here that have done this before. What worked well for you?
