I need help... We have an old 1958 Chevy 60 Viking grain truck and when we purchased it...we come to find out that the rear hold down spring was broken. We have been able to locate the springs for the front...but NOT the rear back brakes. We need to get the truck back on the road so that we can use it for our work.. but no one can locate a simple spring for us. I have pictures of the spring as well as the truck and what the back brakes etc looks like. Would someone PLEASE assist me with this!!!!!!!!
