Would an accurate discription of you goal be, "To create a direct-swap spindle component that requires no additional steering or suspension modifications other than the purchase of new rotors, calipers and master cylinder."?
That is partially correct. Here is an answer to a similar question on FYI Ford. krash, note the last sentence.
There are 4 main advantages for these parts.
1. The obvious fact is that they are new castings. They are fabricated from grade 1045 steel, not iron, and are not fatigued or spun from 40 years of use. And before someone pipes in, Ford steering knuckles (we call them spindles) from that era were CAST not forged. These will be investment cast; a method that yields a product that has a better finish than the original sand cast method.
2. They are more heavily constructed than the early spindles, and the pin (the part that the bearings mount on) are the larger size that was used in 70-73 and Granada. The heavier spindle pin is ideal for large width tires.
3. They allow the use of the larger and economical 11" rotors and calipers from Granada or 70-73 Mustang.
4. These spindles were originally engineered for disc brake application, unlike add on brackets systems used on early spindles.
I am doing this work because Granada spindles are becoming hard and expensive to find in commercial quantities, and they require considerable effort to refurbish to acceptable commercial standards. I am also reluctant to sell used parts. The new spindles will be QC'ed by acoustical analysis and sample Xray analysis.
I will soon begin working on a spindle that is Granada like except that the steering arm geometry will be the same as 65-66. I will eventually offer caliper brackets which will allow the use of 70-73 style calipers and perhaps late model Mustang calipers, although my interest is in providing an economical reliable disc brake swap for the typical Mustang owner's use, not in performance parts. I am aiming to provide a complete swap kit made from all new parts that includes the spindles, dust shields, bearings and seals, hoses, mounting hardware, calipers (refurbs)and pads, and slotted rotors, adapter fittings, and a true drum/disc combination valve for less than $550 or $625 with outer tie rods and master cylinder.
