generally adding most factory options such as - disc brakes , bigger sway bars , better springs/ torsion bars , Ralley Wheels , Shaker hoods , rear window louvers , trim , racing mirrors , ralley dash , larger engines , 4 spds will all add value for most
while non factory upgrades , tubular K frames & rack steering , air suspensions , 4 links , cutting the body for suspension or tubs , aftermarket hoods , spoilers , grilles & to a lesser extent wheels as they can be changed in minutes will detract
