What is the purpose of the under hood fender braces on some of the cars?
Doesn't seem to be a real reason I can see.View attachment 1716340853
Something to add cross brace and also something to add bling when triple plated.
Im wonder what other Mopars used them as was looking for some from a more common car to grab them from.
