champion spark plugs

i was at part source today looking to get new plugs and wires. the champion spark plug book has 57-58 and 60-66. why is there no 59? the plugs in the fury are ac’s and i need to know the proper champion plugs for the 59 318. i ended up with RJ14YC plugs. im pretty sure these are correct but let me know if they are not.
thanks
curt.

anyone ever use champion spark plugs???

Accoding to Champions web site,thats the correct plugs…

thanks Bob.

You probably already sw this, but in the 59 Supplement, it says to use AR42 plugs. It does not, however, list the manufacturer of these.

AR 42s are Autolite plugs…
