Ford Mustang Power Steering System Details 1966

Umbau auf Servolenkung beim 1965-1966 Mustang : 
While there are a few parts that can come from other model Fords, the critical parts must be from the correct year Mustang to work properly. Maintaining proper factory linkage geometry is important for proper operation. Using linkage assemblies from Falcons, Mavericks and Granadas will not work properly, even though it may look similar and physically bolt up. 
To do this properly, you will need the following parts from a 1965-1966 Mustang V8 equipped donor car:

* indicates special high performance applications such as GT, Boss, Mach 1, etc.

 - The steering boxes are identified by a tag attached to one of the steering box cover bolts.  Use the number of turns to verify ratio.

 - Early (64-70) Mustang power steering is of the non-integral, add-on assist type with a separate power cylinder and control valve.  There is no difference between the manual and power steering boxes, except for ratios. The fast ratio manual steering box is the same as the power steering box.

 - 1964-1970 Mustangs have two basic ratios:
1. 19.9:1 ratio, 4 5/8 turns lock-to-lock, used on all low performance manual steering cars.
2. 16:1 ratio, 3 3/4, used on all cars with power steering and on manual steering high performance cars (Shelbys, Bosses, GTs, Mach 1s, etc), optional?

 - 1964-1970 Mustangs have two shaft styles:
1. 1964 to early 1967 boxes are the long shaft style where the box and steering shaft form one unit.  There is no coupler, the shaft is one piece from the box to the steering wheel.
2. Late 1967 through 1970 are the short shaft style.  There is a couple between the box and the steering shaft.  This change was made to meet Federal Motor Vehicle Safety Standards (FMVSS) which required a collapsible steering column.  Sector shafts were either 1" or 1 1/8". There are four different '67-'70 short worms used (2 ratios, 2 sector shaft diameters).

 - The Ford steering box is internally (external housings are not shared) a GM Saginaw manual steering box.  Since the Ford steering boxes use Saginaw internals, many GM parts interchange and some can provide performance upgrades.

 - 1971-73 Mustangs with power steering use either a Saginaw or Ford integral power steering box.

 - 1971-1973 manual boxes used a differently shaped external casting with a 1 1/8" sector and 24:1 ratio.  There also used a slightly different frame mounting bolt pattern they won't interchange with 67-70 models.

 - The 71-73 worm and rack assembly is identical to the 70-82 Corvette piece.  The Corvette sector (GM P/N 7812838) and worm (GM P/N 7812942) will fit in 71-73 1 1/8" boxes if a new groove is scribed into the Ford pitman arm that corresponds with the index on the GM sector and if a Corvette coupler (GM P/N 7806391) is substituted for the Ford rag joint.  Provides 16:1 ratio rather 24:1 ratio.  Also the flat Ford-style sector shaft cover can be replaced with the 'Vette cover (GM P/N 7806748) which has an integral bushing that lends additional support to the sector shaft.  The outer rim of the bushing support must be turned down to fit in the Ford box.

Notes and Substitutions:
a) All 1961-1967 Fords used a Control Valve Housing with a 1/4" pressure port. A valve housing from one of these cars may be substituted if the original is not rebuildable. Although much easier to find, use of a post-1967 valve with the 5/16" pressure port is not recommended because it would require a non-original style pressure hose or an adapter, which would cause an original hose not to fit correctly.
b) Power Cylinders from other models may look the same and physically fit in place of the correct cylinder, but they are not usually the correct length at rest or at full extension. This can throw off the leverage of the power actuation and limit linkage travel. The bracket that connects the cylinder rod to the frame is basically the same on all 1965-1970 Mustangs and the early Maverick brackets will work as well.
c) The control valve doesn't care what pump is providing the hydraulic pressure. It is possible to use the pump and mounting brackets from another car in a conversion. A common setup is using the pump and brakets from a 1967-1969 Mustang/Falcon/Fairlane with a 289/302 engine. Just keep in mind that original application pump hoses may no longer correctly fit the pump of be the correct length, and special hoses may need to be made.
d) The power steering pump is powered by the second-from-the-back pulley on the crankshaft and runs over the water pump. A double-groove pulley is required if you do not already have one on your car.
e) Likewise, you may need the donor car crankshaft pulley if your car doesn't have the proper pulley to run the accessories.
f) The frame bracket threaded inserts are not found in Mustangs that did not come with factory power steering, but the holes for them are already there. Since these are not removable from the donor car, you must purchase new ones to install.
g) Always check the alignment of the pump pulley with the other pulleys on the engine. Ford often used different pump pulleys depending on other accessories used on the engine. While these were generally pulleys of a different diameter, some pulleys had different depths and alignments. 
You will not need the following parts in the conversion:
a) Idler Arm or Pitman Arm
b) Steering Box (the steering box is physically the same, only the ratio inside is different. Using a manual steering ratio box in a car with power steering will make the steering effort even easier than a regular power steering and will lessen the sensitivity of the system).
c) Passenger side Inner & Outer Tie Rod Ends and Adjusting Sleeve
