installing posi carrier - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 67 with a 4.11 posi rear and have wanted higher gears for a while. I found a 3.73 open diff, but would like to keep my posi. How difficult is it to swap in my posi carrier into the open diff. I have had people tell me that they just swapped the carriers using the shims that were on the carrier they were swappin in. What are the chances of doing that? I could also swap the gears into my existing rear axle onto my posi carrier if there is a better chance of success. Let me know if anyone has done this swap.
Thanks
