im wondering if the 86 mustang is the only one to use autolite 2545(or equivelant) plugs if not any idea which 302's used these plugs,thanks

 

bump in hopes to get this answered

 

i have a 1980 block with 1979 internals i have no idea what the heads are from but the spark plugs are autolite 2545 and i cant find any other 302 but the 86 that these go to i tried the autolite ap25 but they wouldnt even screw into the head im trying to find the equivelant so i can buy a better plug
