I have a 68 non-AC car now with Vintage Air. Running hot. Radiator checked out. New larger fan, 180 thermostat and AC rated water pump. Next I suspect adding the baffles are my best bet. I understand the upper filler panels and lower valence, but not the masticated filler panels. Despite the great pics in this post, I am disoriented without obvious external landmarks. Do they go on the sides of the radiator? What gap are they filling and what exactly do they attach to? The repro upper panel comes with fasteners. What about the lower valence and masticated panels? What bolts or clips do I use? Thanks
