instrument voltage regulator

Which regulator works for the 67- 69 Barracuda rallye dash. They sell 2 different models, IV3 and IV4

Neither are a drop in replacement for a rally dash. You need to do some mods. There are a bunch of threads on this.

I have used both of the ones in pictures below. They are both from Amazon. One is adjustable & one is fixed 5 volts. These are easier to use than a 7805 if you are not good at soldering.
