Hello! New member here. I’m MystifyMe. I inherited an 86 Mustang Fox body ragtop with fuel injection and new stereo with woofer speakers. I am in need of a new battery but not sure what to get! Any help is appreciated! Was my late father in law then passed down to my late husband now mine. I had it out like 5 years ago but not since. Looking to get it out and about again just need guidance.
