Here maybe this will help. This is how I made the watts link on my truck. I also had to have a 9" Curry rear with 12" disc brakes.

I know this isn't the best pic for the watts, I will try to take another for you this afternoon.
Also, if you not going to be making that much power then the stock rear end should be fine. I didn't have a choice with my truck as the 800hp the turbo 363 is putting out would break the stock rear into tiny pieces.
Even if you go with a turbo the stock rear should be enough since a turbo 4 will make good hp it won't make huge amounts of TQ, and its the TQ that would be bad for the stocker.
Keep up the good work.
