IF the shop might claim they don't know how to do them, ask if they know how to put shocks on a similar model year Camaro or Firebird. SAME thing, more than they might expect.
If you bought high or mid-pressure gas shocks, then the lower control arm might need to be separated from the knuckle, for which an extra charge might happen. THEN they might also want to do a front end alignment, too.
I'm suspecting any shop doing work for the public will have a rack rated at 10K Lbs, usually. Ought to handle an upper-4000lb Chrysler just fine.
Enjoy!
