Sounds interesting. Should look nice. Are you planning to paint it yourself? A careful airbrush may give you what you're looking for. I've got a nice airbrush laying around. I'll be interested in seeing what you come up with.
Is this the same size 124 emblem as the one on the trunk? I had a spare and temporarily attached it to the Abarth's gunmetal trim on the right side of the dash. I took it off after a day because it seemed too large. I'd like to find a smaller one.
