I wouldn't bother with the stock replacement. The quality is not great, and they cost $100 more than a 3 3/8" autometer. I'm going to buy this one for mine to replace the reproduction one I have
Stewart Warner Heavy-Duty Series Tachometers 82171. I think it looks a little closer to the original than the autometers, and I have the mopar guage needle paint to take care of the white needle.
