Two-piece drive shaft

Any good articles or write ups that anyone is aware of that will shed some light on setting up pinion on a 2 piece drive shaft? I've been reading all of Max's write ups and various stuff online, but most everything seems to focus on single driveshaft setups. I've done singles and understand all that goes with them, but the 2 piece is confusing me a bit. Any info would help out. Thanks!

I start by shimming the trans to get it a little more level, then set the first shaft with 1-2

Right on man, good stuff. Thanks.
