Wilwood Front Disc Conversion 63 Valiant

I put this kit on my '70 duster excellent upgrade..I used the Wilwood master that looks like a Mopar unit and the Wilwood proportioning valve..not sure about keeping the stock master,had no intentions of keeping mine..
Hey,
Don't want to keep the stock master, just want a more stock looking one. Don't want the Willwood master as it is not the look i'm going for. I did notice too that the wilwood masters are two bolts through the firewall, whereas mine stock on had 4 bolts.
Did you add a residual pressure valve for the back?
