In the quest for better street handling, I swapped from a stock steering gear in a 73 to a Mach 1 gear (the variable ratio steering gear). But it still isn't quick enough! There are 12:1 gears available at http://www.agrsteering.com/ but it doesn't mention if they are the correct bolt hole pattern for the Mustang. Kinda peculiar that the 71 to 73 uses a Saginaw steering gear! Anyway - does anyone know if any GM gearbox has the same bolt holes as the 71 to 73 Mustangs? (It is supposedly the same internals with a slightly different casing for different applications).
