Vintage. I know the book states that you really don't have any adjustment except for toe, but when I got my Z I found there were shims in my right front on the (2) lower bolts for camber (3 each). When I finished installing my new struts and setting my ride height, the shims were required but only one on each bolt. I eventually slotted the top mount hole in my left front strut due to I had to much camber and had to take about 2degs out of it. Friend-of-the-working-man Randy Forbes also let me know that they make a crash bolt, which is slightly small in diameter to allow for more adjustment. I didn't have to go that far and used the stock bolt. Worked perfectly with no shims in the bottom. I know I have to replace the ball joints and bushings, but that will take place later this spring. I figure I'll be doing this all again, but until then I'm now not worrying about tire wear and the car handles great. Anyway, just my couple pennies worth.
