Front disc brake conversion on Demon-Now alignment is way off. Needing help!

You've just changed the track width and also the pickup point for the outer tie rod as the lower ball joints are a bit different shape.

The fact of the matter is, regardless of what they say, you'll need an alignment. I did the 73-76 conversion that takes the same parts like 14 years ago and put everything back to where it was originally (cam bolts, etc) and it was way off.
