You could buy a tach from sun pro for much less money. Rally pac is more for show- although I have one for my 64.5 convertible (scott drake re-production). If you want one be prepared to spend upwards of $300, and the one you would want for your '66 is the low profile model. I have one, I thought it was worth the extra expense. John
