SAI way out of alignment spec

I just had my truck aligned and they told me everything was in spec except the caster on the passenger side so I went on my way assuming it was my 2" lift throwing the caster off. When I got home I noticed a read out of the alignment specs stapled to the receipt and realized that the SAI and included angle are pretty far off spec on both sides. SAI: 8.7 left and 13.9 right (-5.2 cross SAI) while the specified range is 9.9 to 11.4 ... Included Angle: 8.2 left and 13.1 right while the specified range is 9.3 to 12.3). The truck drives straight down the highway and doesn't pull either direction and I have no unusual wear on the tires. I put Bilstein 5100s on the truck about a year ago and had it aligned then but don't remember if I got a read out that time so I can't compare them but don't remember anything eye opening like those numbers.

Can someone more knowledgeable than myself please chime in here if there is something that commonly fails in 1st gen tacos that would cause these numbers? A search found nothing.

If the weather's alright tomorrow I'm going to have a closer look at everything ... hoping it's not anything major.
