When was power-steering available on the Mustang?

Power steering was available as an option for all 1st generation Mustangs (1964 1/2 - 1973). Some special models (i.e. Boss 429, etc.) offered power steering as standard equipment.

Yet another $.02 worth from a proud owner of a 1970 Mach 1 351C WITHOUT power steering option @

Well the power part is pretty much the same now as then ( hydraulic) but newer cars have better actual steering gear. Mustangs have had rack and pinion steering since 1974 which is far superior than the old steering box systems of the original cars. Generally speaking power steering is standard on most cars, whereas years ago it was an option on lower end models so many cars were built without it. StuK
