This driver side radius arm is the early style 2WD version which bolts to the bottom of the control arm rather than threading into the arm.

Fits 1980-1985 through chassis number F 24 F 019682.  1985 Vans: please check to be sure that this is the style of radius arm you need. 

Consider upgrading to Powerflex polyurethane radius arm bushings when re-assembling your van's front end for excellent performance and longevity.
