no melt design 90 degree plug wire ends for 7mm plug wire and snap end distributor cap ends. plus 8 vari angle plug wire ends to fit other applications. these terminals were designed to work with solid core 7mm spark plug wires. had a set on my 64 Chevelle race car
and they worked very well. That car with a small block had a problem melting spark plug boots. the distributor terminal end kit made it easy to remove the wire from the cap for a quick disconnect and a very positive snap in fit.
