I'm installing a 4 in. z lift on an 04 cc. I have done a lot of bolt on lifts. but this is my first cut frame lift. ? is about welding the extension on the steering knuckle. Looks like you have to weld the extension between a male end and a female end. What do you do ?stick the pipe over the male end, weld that, then center it up on the female and tack it then weld? I was thinking about putting a drift or a bolt in it to center it all up first on the female end. Any ideas?
