Good for all 1965 thru 1972 Corvette & GM TI distributors. This part repairs the Magnet assembly. Finally a simple Great Repair to TI distributors= you no longer need to purchase an Expensive magnet assembly. Note: 1 or 2 cracks in the magnet has no affect on the Distributor at all. This was proven by Magnet Aerospace Engineers 20 years ago. 1965-66-67-72.
