I had a nice C4 corvette once upon a time, and while the alignment specs were debated ad nauseum on the corvetteforum, and there were a few schools of thought about what was "best", it was possible even though the front and rears were different- and nobody charged nobody an extra $120 to dial them in. And- I'd find another shop to work on the 190 for you- he likely used a torque wrench to re-install your wheels/tires after the brake job- and is now whining that they are on too tight, which is why he can't get them off now.
