Coolant reserve system decal position
This image shows the placement on my 1973 Duster Twister. I replaced the original in this spot. The decal barely fits in that area.
Factory placement can vary some. I've seen some further toward the driver side. Note that my Duster has a 1974 coolant recovery tank. When I replaced my yellowed original in the 80s, 1973 tanks were no longer available new, nor reproduced, bur Chrysler still had the 1974 tanks. So, I switched to that.
