508750 Big Twin ignition distributor. 1-hole. Chrome

This chrome-plated Big Twin ignition distributor from MCS is a high-quality reproduction that brings modern reliability to classic machines. It is designed specifically for 1966 to 1969 Big Twin models that utilize the single-hole mounting design. While it maintains the authentic vintage look, it has been upgraded internally with an automatic advance mechanism to ensure smoother performance across the rev range. This unit comes complete with all necessary internal components, making it a straightforward replacement for OEM numbers 32502-66A and 508750. It is a great way to refresh your ignition system while keeping that polished, period-correct appearance on your shovelhead or late panhead.
