Just wondering about the significance of the two holes in the side of the arm. My original 68 arms don't have them.
The arm is supposedly NOS 69 camaro.
Also, the shape of the support bar is different, the loose one in the pic is of my 68. The one attached to the arm has a number cast into it, which as best as I can make out reads 381904.
Is that a 69 casting number?
Is the loose one the correct shape for 68?
