Back to the distributor cap. My engine came from Roush with a MSD-83541 distributor that incorporated a small dia. black cap. When I went to replace the cap ( after cleaning up the old one for a spare ) I found that the red cap was readily available, but not the black. I finally found one at an Offroad 4x4 supply house. Do not know if this still holds true today.
