Alignment Problems

Hi I am kinda new to this sight but have noticed that there is alot of helpfull info on here and was hoping that someone in moparland can help me not sell my Dart. I recently finished the frontend on it all new moog suspension parts it is a 72 Dart 318 4 speed with 10 inch drums front and rear, everything is new! I took it to my shop I work at a Dodge dealer and Im a tech there, I put it on our alignment rack which is the newer updated version rack. I was able to get the toe, camber, and caster within specs but when I looked down the chart I noticed that the SAI (steering axis inclination) was in the red. Now I know that they use specs from the older bias ply tires but dont understand why this is. the specs for the sai was 7.3-7.8 and mine was 6.3. Also my included angle was out of spec.
From what I read it said I could have a bent front end part????
I was hoping someone could shed some light on this for me. Also my caster was within spec but was -0.5 and I thought you should shoot for negative. Any help would be much appreciated. :banghead:
Thanks in advance
