Yes, when you alignment shop sets it to 30 year old specs and you wonder why it drives as bad as it does.
The spec above work good on all the older mopars !!

I have RMS upper arms and around +5.5 of caster. The car drives like a dream setup that way.

Most shops need something to put in the machine, 2007 Mustang matches specs posted above.
05 Mustang GT specs are -.75* camber, +7.1* caster ( which you wont achieve with a mopar, but take as much as they can get while offsetting the camber spec) and .1* to .2* toe in , which on a 26" diamter tire, is right about 1/16" total toe in. I know there are some shops out there that will only use the specs that are in their computer and they will not tackle a customer provided number. Using Mustang specs give them a late model input and a target to shoot for.

Finding a good alignment shop can be harder than getting a good alignment.
Seems you found that out.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Heck with a stock front end its tuff to get even 2 degrees of positive caster. I put as much positive caster in my 63 as I could when I aligned it and 2 degrees positive caster was about the most I could get out of it with the stock front end parts I use and setting the camber from 0 to .5 negative. I run my toe about 1/8 toe in and I run radials front and back. And it handles good as it drives so much nicer on radials. I like the radial slicks at the track also as you run more tire pressure in them then we did on the older bias slicks as I run about 18 psi in my radial slicks at the track and it goes nice and straight. With the older bias slicks most cars would wonder a little at the top end. Course we used to run them from about 6 psi to about 12 psi. Its also so nice that radials dont follow the lines in the road like bias tires. You run radials on an old muscle car and compared to having bias tires on it the car will feel like a different car since the radials drive so much nicer. Sometimes I wonder how we drove our older cars on just bias tires back in the day ? Ron

Finding a good alignment shop can be harder than getting a good alignment. Yes you might want to consider aligning it yourself. "stringing" it on some tiles to get it level then setting the toein to 1/16 then with the cams already turned all the way for max caster, bring the rear cam on out till the camber is zero (a cheap carpenters 2 ft bubble level with 2 sockets superglued on it & the level/sockets then superglued to the rim), (your weight in barbells in the dr seat/half tank of gas/tires aired up). #1 get the ride height to where the front tire clearance looks good to you. let the caster fall wherever it may be. You might even do this then drive it several days to let everything settle then redo it but even 1 time you will be fine. there are some utube vids to help with this.
