Here is the name and address of the shop:
Autofficina Petrini Igino & C. s.n.c., via Salvemini 7/b, Jesi, Italy
Let me know how you make out, and give my regards to Sr Petrini.
He will remember me as the American who bought the silver GTV-6 from a client of his.
He fixed my fuel pump on a rush basis so my daughter and I could continue our trip around Italy.
