I wanted to bring this to anyone's attention that may be searching for a 66 GT350 tach. If you want one that will pass for a original this is not it. I don't think Branda has a dishonest intent just a lack of awareness of differences. https://www.ebay.com/itm/234679419819 The needle is a very visible difference IMO. I am reposting a comparison picture Cory posted recently to help see the difference. The 4 wire installation is another easy repro tell. No wire on a original 66 goes out to coil, green or otherwise. I sent a note to Anthony at Branda to maybe modifying the description. Branda Performance is a very valuable part of our Shelby marque community IMO.
