Ed...I ran this by the guys at VCCA and this is the response.That is where the front of the front leaf spring mounts on a Master.The Master Deluxe with knee-action does not have this.Moose
I looked through car pic's under 37 chevies and could not find one 37 chevy with those brackets mounted on the frame. I don't believe they are for leaf spring mounting, they are kind of narrow for that, but I have been proven wrong before. What suspension is under the 37 now, is it the original knee action?
