Yes I aware that the regulator would need to be replaced wether it is worn and I keep the 90 amp alternator or if I go for something larger. Also forgot to mention the battery I have is much bigger than stock its rated at CCA 850 and CA 1000, replaced in December 2018 and the same specs as the prior battery the previous owner had in the car. It is healthy and been on/off a maintainer since I pulled the fuse box.
