I know this isn't a TBird forum, but I'm hoping someone may be able to help. My 1955 Tbird has stock manual steering.  A friend has two complete power steering setups from a 1957 and 1959 Ford Y Block passenger car. Will the passenger car parts bolt on my TBird?  Will I need to change the pitman arm?  My car steers fine at speed.  I am looking to reduce the steering effort required when parking or turning slowly.  I want to use stock parts.  Thanks!
