Hello, Newbie to the site

Hello Again... Ive been having a fun with my new Toy, cruising the threads here and surviving in a WFH environment. Ive noticed that my Car has been called a "Survivor" by Folks here and my Friends, and I get the reference, and that got me to wondering. Do I keep it completely stock, OEM so to speak, or can I do minor bolt on w/o violating the spirit of the Original? Things like new ignition, 14" rims and tires, swapping the Master cylinder for a dually?? Installing a Dome light? Front disks? Pump Window washer?? If for anything, these upgrades seem like solid safety/reliability things to do.

Just thinking out loud.
