Ah I see!
I did a search for '67 grille before I asked ..great post and the photos are helpful....sdkar may help you visualize as well.
My (2nd) NOS replacement is a '68 style- no surprise I guess...I had been told about the difference before but wasn't sure exactly what it was.
A woman backed into me in about '76 so my original is replenishing our oil supplies in a landfill somewhere in eastern Washington...looks like others had this same experience in the '68 thread.
I bought a replacement then as well...its in the attic- I'll have to look someday to see what version it is...thanks again..
