I just got completely through your thread up to this point! Again
EXCELLENT--the truck, the thread, the inspiration, the pinups
, all of it! You should get a gig in PR, or instruction, or something like that!
This video from Wilcox Corvette about tach restoration tells you how to "zero" a factory tach. If the truck tach is similar to the one in the video, it might help you on the one you 'stole' at Pate. It's an electric vette tach, not a mechanical.
