I have not been able to find a brass drift locally or have been looking in the wrong places. I used a piece of square aluminum tubing to get the hub races in and it worked like a champ. I am in the process of getting the drag link out of the way so I can get the upper knuckle races in. I really didn't want to do that but that's the only way you can check the preload and get the upper race in.
I do like the idea of using the old race upside down though.
Any suggestions on the Easiest way to remove the connections on the steering arm rod and drag link? And get them back in?
