From the book cited in #2 above.. The upper shock arm in the photo is for the front of '32 passenger cars and commercial vehicle and it is 6 5/8" in overall length. The lower arm in the photo is for the '32 rear shocks and it is 8 3/8" in overall length. The links on the left in the photo connect the ball end of the shock arms to the axles.
Corrected...Pete,
With respect, those are Model A shock arms. The '32 versions lack the shoulder behind the ball.
