Try Autozone, O reilly, napa.. you will be surprised at the number of parts new or rebuilt that are still available for pintos since Ford tended to use the same parts across a lot of models including the mustang ii and ranger.. the weber 2 bbl was used from 71 till 92.. the only problems seem to be front suspension and brake parts for 71-73 models.. later models share a lot with the mii.
