Tire shop over torqued lug nuts (1969 Dart). Should I redo it?

Yes it is the correct answer, yet when you make the suggestion they go get a factory service manual for their car and learn to work on it themselves, a lot of them act like they need to go hide under the kitchen table for a safe space. People who buy old cars and expect not to do any work on them are fools.
I'll probably let a tire shop work on my Camaro when tire time comes. They definitely work on my pickup or box truck, tires are too heavy for me to bother with (roughly 100 lbs each, on the box) Torque on the box truck studs is something like 125 lbs.
But tires on my rr, or savoy, or Tina, or Opel? Tires are going to a specialty shop, loose in the back of the pickup, and getting put back on the car by me!
