I have a new Accel one for sale. Billet housing,high quality Accel cap and rotor,plugs right into the MP harness. Part # 59301 if you want to any research on it. $125 plus shipping.
Still looking ? My customer has one that I just took off,excellent condition ,with a timing tape. Make an offer and I will speak with him about it. We removed it to install an SFI one with the new combo.
