Be aware that the Imperial Services PB conversion works best on '62-'65 TF's that have the Park feature. On pre-'62 there is no provision in the PB shifter to engage the park mechanism. On my '57 NY, I connected a '62-'64 PB cable to the '57 shifter and mounted a separate '62-'64 mechanism under the dash to operate the park cable and engage the park mechanism on the tail housing.
