On the master cyl. I painted mine with Stainless Steel paint. Makes a shiny bare metal finish. One bit of warning on a problem I had on my truck, after having the wiper motor out. When I put my wiper motor back in it was out of phase with the wiper postion on the windsheild, so when I hooked up power back to it (hooking up the battery) the wipers came down onto the cowl panel below the windsheild. Luckly not scrathing but they sure could have. I took the wiper arms off, turned the motor on then off so it would postion itself, then reinstalled the wiper arms. Thought I might pass that along to you because I see you have your wiper motor out and that might happen to you. Hope that helps you.
