Steel core all the way.
ABS cores look all warpy in the vent area and every screw will strip out on you....like the speaker grill and other trim.
Warpy in The windshield vent area or a/c vent? From 1-10, 10 being warpy like a potato chip, how bad is it?
Is there a steel core option anywhere in the $500 range other than a dash cap? I really like that this one should be a short lead time and I don't have to send a core back and forth.
The screw stripping isn't a major concern, I can work through that.
