I researched and found that Powermaster makes a model that will actually bolt on the existing mounting points off our ’62 engine block; no hunting around for ’63 mounts. It comes with an internal regulator; and only in a 90 amp option. It only comes as a single-wire configuration – not sure if that is a bad option. Jeggs will provide you with all the correct wiring and terminals required along with grounding straps. I hope to install this in May time frame, so hopefully its as easy as they say it is.
