The steering components are the same on all passenger cars from 1954 through 1956 including 55 through 57 T-Birds.  In 1957 and later passenger cars, that all changed.  There are parts that are Thunderbird only.  Pumps may be the same but the pump tops are lower as well as the mounting brackets to allow for lower mounting.  Hoses, idler arm mounting, and some other small parts are T-Bird only.  Pitman arms (power and non-power) and drag links (power steering) are the same for T-birds and 54-56 passenger cars.   For me I would get one of the power steering kits in the catalogs for the 55-57 T-Birds.  They are pricey ($3000.00) but everything you need is there and parts are either refurbished or new.  I did this several years ago (10 - 15) and it made a big difference in driving the car.  At the time, it was $1800 from Concours Parts.  As with all old car parts, sticker shock is the norm.  Good Luck.

The brackets may be different because of the spacer that the Tbirds use at the waterpump, but it looks like they are available looking at CASCO's catalog

I don't think the pump part number would make a difference they bolt up to the same Y-Block. I would think that the steering arm and drag link may be shorter but I'm not sure.

Y's guys rule!

RockAuto uses the same part number for the PS control valve and cylinder (ram). The PS pump numbers are different. At least some of the parts are interchangeable. 

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!
