Over the winter I plan to replace all the suspension bushings, ball joints and rod ends in my '79 BB512. Although the car feels fine, the rubber bushings are looking a little dried out and brittle. While I'm at it I'll anodize the A-arms and hardware, rebuild the shocks, re-coat the wheels and refinish the exhaust. A couple questions ensue. 1) What is the proper color and texture of the factory ANSA exhaust on a BB512? I have seen the headers a white rough finish. Is the muffler supposed to be the same, or black? I have an excellent rough white coating on the exhaust of my Ford GT that has held up exceptionally well for 8 years and am inclined to use that same process. 2) The A-arms? What is the proper color? Silver with a little gold? 3) Wheels? The wheels are showing some bubbling of the paint and I might as well refinish them while I'm at it. As they are magnesium, what is the proper process? It obviously didn't work so well last time. I know aircraft with magnesium filght control surfaces use a special procedure / primer before applying paint. What do you guys do for the magnesium wheels? I appreciate all help and input.
