I ordered a new radiator core support pad & it arrived with two flat rubber pads. Is the correct sequence "core, pad, washer, spring, washer, pad, frame, nut, nut"? How tight should the assembly be; just so the springs are slightly compressed or fairly tight? It must have been too long ago when I took stuff apart because now I'm a little fuzzy on certain details. I tried to take photos of everything before disassembly but typically the one I need (for now) isn't there. Thanks for your help.
