my shaker has 3 holes, but when I picked up the car in 1994, it only had 1 callout on it, with 2 prongs. I picked up a few NOS ones, but they were 2 prong emblems also. I've never seen a 3 prong emblem in person - but all the ones I have are brushed, not shiny. I'm sure my shaker bubble is original - looks like it has some time on the job, has some of the over spray on the underside, part #, and is in pretty used condition, and as far as I know, the repro's weren't out yet - Joe
