I have never seen one that has a cap like this and anyone know anything about it. The cap does not look complete or I would think about buying it to put on my 37 just to be different.
VCCA members have access to a list of over 50 Technical Advisors who can help you with your car. It's worth the price of membership! While you can get a lot of information for free in this forum, sometimes the info that you REALLY need is only available from the right person. This is what "The World's Best Chevrolet Club" is all about!
Just a guess but maybe truck like COE or something like that.
