Oops, You are correct, my bad. I was trying to go off my memory which is scary sometimes. I've seen people make their own templates going strait down instead of offsetting so please make sure your hole positions are correct. this may be why he's having trouble adjusting. I also adjusted my own except I used a combination of digital levels and squares but for my toe in I have an old bar type alignment gage left to me by my father in-law
I added a .015 shim all the way around
the camber is already noticeably better and doesn't seem to wanna pull all over the road as bad, maybe that parts in my head though.
I bought one similar to that, but from amazon. I used greased up trash bags as turntables to set my caster. I didn't know this till recently when I talked to someone in the know but the specs he left me with, -1.5 caster on both sides is really dangerous and was causing me to get pulled all over the road. From the mustang expert i talked to he said that using adjustable strut rods to adjust caster would bind and ruin the lower control arm. Now that I know more I realized there was plenty of threads in the engine compartment off the upper control arm to adjust the caster with I could have called him out on, but the more you know. The only issue I am currently having and how he may have been a little right is my camber is not staying consistent. will change a half degree or so depending on when I measure it so still not sure whats causing that. I am about to work on measuring my toe, but i'm guessing it won't stay consistent either.
I bought a tool very similar to what's linked on here but I bought it from Amazon. Did it myself in a garage with a buddy with some greased up trash bags so the wheels would turn side to side some what easily. So far I've gotten more than 1500 miles on this new set of tires and no unusual wear compared to after 100 miles I could already see the wear after the shops "alignment" The shop was definitely screwing me. I'm sure it's not perfect as I eyeballed the toe but it's decent enough for the limited driving I do. And bonus it doesn't try to pull me into the ditch after every bump
