Bob, in case you are still looking, but not close to New Haven:
Maple Tire Center
63 Windsor Ave Route 83

Best to call in advance and make an appointment.
Two man shop, they personally do the mounting, balancing etc. I have used them for a number of years, the last time mounting the forged Fikse wheels on the Corvette
