this economy gauge

67-69 B-Cudas came with either a Tach (kinda rare), a vacuum cage, a clock, (rare) or nothing This is on the right side of the speedo. I hope I am remembering correctly. My 67, and 69 both have vacuum gages. That vac gage, in your pic is for a 66 B-Cuda I believe, unless your pic is out of whach, cause it looks to big to be a 67-69.
