Numerous questions on my car's power steering and Formula steering wheel. Some say the Formula wheel was not available on manual steering cars...others have told me that manual steering was not available on any Formulas. My sources say that in 1971 power steering was available on any Firebird (including the Formula) as option 501/N14 for $115.85, except on the Trans Am, where power steering was standard. As for the Formula steering wheel, my sources list the Formula steering wheel as available on #'s 2487,2687 (Formula), and 2387 Firebirds as option 464/NK3 @ $42.13 regardless of manual or power steering, and as standard equipment on the Trans AM. My build sheet does not list power steering, the #1 owner said he had power steering dealer installed, and my car has not-correct-year power steering on it (possibly from a 1969 dealer kit). Attached are some pix that folks have been asking about: Axle,Trans, Motor #'s all matching last 8 digits in VIN, and PHS documentation.
