I would like a kinda quick advice for tomorrows visit to the dealership, if anyone feels like it

My recently acquired 07 EB EL w/16K , bought Pre-owned (kinda like used, but more sophisticated ). I didnt like the steering effort and very slight feathering of the fronts. Also just wanted the alignment checked, doubtful that it had ever been checked. Overall, I am very pleased with this vehicle, including the power of the 5.4. The gearing makes this engine perform well.

Alignment guy says passenger side is considerably off (dont recall deg exactly--seems like it was ~ 8) believe it was castor.

Service guy says OEM bolt/cam mechanism (I dont know exactly what they look like--yet) will not correct that range. In further questioning by me, Serv adv says that the OEM setup is not adjustable (What the------). Therefore I need this alignment bolt kit that does both sides. I hesitate to laugh at them because I dont exactly know what the front end setup looks like.

"Shore" would like some input if I can get it
