The one at Chevs of the 40s looks to be a tad wide on line but not in the catalog, part number 3685524. The part shown in The Filling Station catalog is part number 60-12A. The catalog shows it to be 1 1/4" wide. You don't say where you bought the part you have but you might give Chevs a call and ask if they can measure theirs for you. I still have the original in my coupe.
