I've bought alot of parts from Show Cars in the past. At times, I've even spoken with Bruce. Always had a good experience. Unfortunately, as mentioned in another thread, it's just not what Show Cars sell. It's all over. Chinese junk. So, either we accept it, roll the dice on fit or quality, or we don't. Return it if we have to. Search for a NOS, used part. I feel your pain on this. A few years ago, I bought a reproduction, dash mounted tach for my '64 SS. I just love the way these tachs look and fit. Short story, the fit was fine but it didn't work properly. Sent it out for repair and it worked fine then. My buddy had the same problem. Contacted the vendor, not SC, and he admitted to having problems with them. So, knowing that, he continues to sell them, right?? So my advice to anyone buying a tach for their dash, don't even bother unboxing it. Send it to an electronics guy of your choice. Less grief and aggravation. Sorry ,a little winded on this one , Carmine.
