Hood Mounted Tachometer (Obv. Not Stock)

I own a 1965 Dodge Dart 270 Convertible that is finally back in my hands from months of rework, upgrades, and tuning. Long story....

Today, I decided to take apart the hood mounted tach that looks awesome but isn’t functional for some reason. I know it’s not original and it may even be from a Ford (gasp!). Not really sure.

Knowing that we have some insanely talented gurus in here, I thought I’d post some photos and get everyone’s opinion on where I should start with fixing this. Let me know your thoughts!
