Scored 2 sheets of 3x2 a couple of days ago actually. The sign had blown over in a storm that we had so I figured that I would "recycle" it. Plan to do a front grill block as soon as I can loosen / break the screws holding the front bumper on. Just an excuse to buy a pair of Vise-Grips
These were common on pre 1980s European spec cars, but with modern thermostats, you do not need them. It is better for you FE to run warm, yes, but do that with a proper thermostat Vs. these, or what my friends in Ohio called "West Virgina Thermostats".
