fitted em up, what a bitch to get the center back into the car lol. when i finaly got it in, the splines on the longer half shaft didnt line up in the final section. what a bitch, back out with the center it came, i did actualy line up the splines like you said, might i add for anyone else doing this. once you put ur shims in put both half shafts into the center completly in, then tighten the 2 philips heads, then leave the shafts in. put ur ring gear over the top and rattle that up with the half shafts still in the center. makes it alot easier and no room for error. the first time i was literaly .2mm off the splines being 100percent. and yet it wouldnt go in all together.... peace!
