Modern radial tires require alignment specifications that differ from the original factory specs developed for bias ply tires. For caster, SPC recommends +3.00° of caster to promote improved return-to-center and more responsive performance. Stock strut rods on the 1st generation Mustangs and FoMoCo vehicles are non-adjustable and often have worn out bushings that can cause excessive movement of the lower rod assembly, resulting in poor handling. A must f or ‘64 -’66 Mustangs on modern rubber, this adjustable caster rod features high durometer OE-style bushings to protect the chassis mount from damage and has easy caster adjustment. It will provide the positive caster needed for improved tracking and modern geometry. If adjustable camber is desir ed, look to the SPC complete control arm kit # 94218.This Part Fits: Year Make Model Submodel 1964-1965 Ford Falcon Base 1964-1965 Ford Falcon Futura 1964-1965 Ford Falcon Futura Sprint 1964-1966 Ford Mustang Base 1965-1966 Ford Mustang Shelby GT-350 1966 Ford Mustang Shelby GT-350H 1964-1965 Ford Ranchero Base 1964-1965 Mercury Comet 202 1964-1965 Mercury Comet 404 1964-1965 Mercury Comet Base 1964-1965 Mercury Cyclone Base
