Yes # 84313, its the same as the red one used in their current production for the Small Diameter Billet Distributors. Distributor numbers are displayed in this link as well as Photo of the Cap. I use this one myself. If you have an early production Small Diameter Billet Distributor, they used two aluminum hold down clamps, they are not used with the new caps. Caps fit early and late production distributors. NOTE: The distributor model numbers shown are not complete. Go to the distributor section and check caps in "Accesories". The 8431 is the red cap (w/o rotor). THen Scroll down in "Accessories" it shows the same incomplete numbers.
