OER 3989447 Features:
Reproduction of the original idler arm assembly designed for use with various 1968-74 Camaro, Firebird, Nova, and GM X body models. This pivoting support for the steering linkage appears on older recirculating ball-type steering systems (pre-rack & pinion) and functions like the pitman arm in a rack and pinion system. This black, cast-iron steering arm features two holes for mounting to the frame, a rubber boot on the mounting section of the idler arm and also includes two fittings and a hex-nut with slots in it to retain a cotter pin.
