Resto-mods appear to get very similar money at auction to original cars. If you had less than 8,000 miles and original paint then it would help the value more to stay original. Most of the people that get these cars want them upgraded with modern brakes and suspension for safety reasons. If you have the storage space, I would keep everything you take off in case tastes change in the future. Having those parts might boost the price with someone that really wants them
