Two of the original crests are sold to Explorerlyon, two remain.
I also have 2 more crests and a hood emblem. Here's pics and info:
Items 1 and 2, good condition, but heavy clear coating on them that is slightly yellowed. These are the two on the left in my previous picture. $12.50 ea. shipped USA.
Items 3 and 4: 3 is original, but is in rough shape. Chipped enamel and slightly concaved (warped). 4 does not appear to be OEM and does not have the holes for a wheel emblem. I found it loose in a car I had purchased. $5 each mailed in an cardboard envelope, or Buy all 4 for the low, low price of $30 shipped (USPS Priority).
Hood emblem. Does not include nuts (I have them somewhere and if I find them I'll include them). Close inspection shows slight cracks in the red portion of the enamel. $35 shipped USA Priority mail.
