Hi All
Fast forward 13 months, I ended up purchasing the Moss aluminum radiator shroud (#855-138) on sale. Arrived today and looks great in the black crinkle finish. I have yet to fit but, it is deeper than the current duct installed in the car now.
Recall, I have a plastic radiator duct purchased from Vicky Brit in 2012. It is 8" deep at the top, leaving a rather large 2" gap around the radiator. This new duct is 9" deep. So, at the very least I can reduce the gap by 50% to 1". Additionally, the holes for the mounting nuts/bolts are slotted with 3/4" play. So, once I go to install, I'll see if this allows me to reduce the duct-to-radiator gap down to 0.25".
We have a "Winter Weather Warning" for tomorrow. Predicted 12"-15" of snow with winds up to 50mph (blizzard-like). So, fair to say it will be a few weeks before I can install this and report back.
