Things you see when you are crawling around under your car!
As I was under my 70 Duster I came across something odd. It is on the rear section of the frame as it loops up over the axle. On the driver side there is nothing but a hole where the bracket? used to be. On the passenger side the bracket is (was) still there, until I removed it. I did some grinding and made a patch plate for the hole on the drivers side. What were these used for? I’ve heard they might have been assembly line jig mounts used during production?
