In need of some experienced alignment help

[jcblue]

I have taken my truck to the alignment shop and have been told I need to do something different.. I have a 72 static drop 5/7 using 3 inch springs and western chassis 2 inch spindles. I will attach a pic at the bottom but as you will see there is a lot of negative camber.. Alignment guys says he doesn't think he can put enough shims in there to bring it out and if he can he said he wouldn't feel right about running it like that.. When the truck was apart I took it to the frame shop to make sure all the specks were right.. I have ordered a set of one inch narrow lower control arms from Porterbuilt but am wondering if that's necessary bc I see so many trucks running the stock arms with what seems to be about the same stance.. Any info or opinions would be awesome
