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. It 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?
