A couple simple things.
4th gen wiper motor. Early wiper switch can be used. Add in proper sized resistors to the wires to give just a speed choice or two.
Brake line flare nuts were bead blasted then used Gun Bluing to finish. Gun bluing works great to blacken various parts plus freshen up factory black oxide coated nuts/bolts. Brake lines are powder coated.
Black anodized washer with stainless flat head screws. Washers available from hillcofasteners.com. Made for button head bolts, I countersunk these.
