Rallye dash Tach retrofit?

I am ordering from classic industries, I’ve waited about 4 months already and still nothing. Might be easier to order from herbs.
I would have to agree. Herbs says on their site that they are about 2-3 weeks behind on their orders. If I was you, Id cancel my order with Classic and talk with Herbs and order from there. Like @S'cuder said, they supply Classic and other business', might as well order right from the source.
As an afterthought, the quality of the tach I received from Herbs was topnotch, I am very happy with it, fit and function is 100%.
