1968 Fastback

Started ripping the front end out this week. It actually is acting like it wants to come out which is a bonus. The car originally had KH Disc brakes on it but he ditched those for drums in 1985, but for some reason he had 9" put on front even though the rears are 10". Its getting disc brakes again but I am using a bracket designed by my father in law who was a Chrysler engineer, which should be getting water jetted in the next few weeks. Going to be powder coating front end pieces before they go back. If you have had pieces powder coated do you ask them to leave threaded portions alone? Planning on powder coating strut rods, upper and lower control arms.
