F body rear leaf spring mounts

I have a 76 Aspen with a 7/14 rear and the plates that hold the rear to the leaf springs and shock is falling apart on both sides.Does anyone have a set to sell or know if I can adapt ones from a 65 A body to it.I have both 71/4 and 8 3/4 plates for early A bodies but would rather get the right stuff if I can.I need this car for work so i need to act on this quickly.Thanks ,valiantwagon guy (Ed)
