Rotor dust shield?

[Neal Molder]

I'm progressing quite nicely with my front suspension in my 68 longbed. My question is do i need a vibration washer or pad behind my rotor dust shield. I've seen in some threads where guys use them. My cpp dust shield did not come with one. Is vibration an issue? should i make something? How important is it? My spindles are from ECE and my rotors ar cross drilled and slotted. My other question is Should i be concerned with painting up my rotors and brake calipers? Is it not necisary? I notice a lot of guys don't bother.
