Does anybody know where I can find correct 76mm pistons & sleeves for a 695ss? I attach photos of why they have to be changed. I also believe that this is not the correct piston for the car. Specs call for a 10.5 compression piston & the siamesed gemelli, gemellati?) sleeves. I am aware of Fiat500sport.com, but I believe that the pistons that they offer may also be incorrect as compared to original. Any help would be appreciated!
