ext cab driveshaft question

I'm setting up my 88 ex cab Mazda right now and had a quick question. What angle would I want my transmission and my carrier bearing at if the rearend is at 6 deg? I know that it doesn't have to be -6 because of the carrier, but what would be a good range to get the numbers in?

There is a good write up on airridetalk.com about driveline angles.
