The Pinto is Puch produced for Penney's, like the Sears Free Spirit.
Mechanical parts will be the same as a Puch Maxi. Controls and cables would be generic moped items.
Pinto specific parts would be a problem, but this Forum and Ebay can be a lead on that kind of stuff.
Yours is a limited production model since JC Penny probably didn't sell too amny of them.
The Moped Forum on moped.org had arecent post on the Pinto.
