Since driving my 69 to work every day (40 miles each way, have to put a new steering pump in my 2001) I have noticed I have a definate negative camber on both front tires. I am guessing some is needed, but should it be that severe that you can see it? Is it due to excesive wear on any particular part. As I recall it's not uncommon with the early twin I beams.
Thanks, God Bless & Happy Easter,

Be sure to verify your springs are good. That is usually what is wrong with old trucks not discounting other possibilities just giving a good starting point.
If you buy a new set of Moog cargo coils it will raise the front end and cure your alignment issues. Your I-beams did not bend (resulting in the negative camber), more likely spring sag. You may need to let the new Moog springs settle a bit and then trim them to get the desired alignment (that's what I had to do ).
Yes check front springs, I got some raised springs by mistake and it gave the truck noticeable positive camber - the higher the springs the greater the positive camber and vice versa...Sagging springs would make it have negative camber - if not then investigate other stuff like ibeams, etc
