Rick if the bottom of the tires are pulled in, this is positive camber. In at the top .... negative camber.
Most shops I have talked with on this first want to bend the housing. (not sure if they want to do it for the $$$ or why
) but I personally do not favor doing that. I have heard of a kit out there that is installed at the king pin, kind of like an offset cam but have personally never seen it. My preferred option would be to shim the spindle
(if you can find shims to do this.... I think they are called cosmo shims) to get the desired camber. Once it is in, no worries what so ever!!!
Hope this helps.
