I just went and tried to get the motorcraft plugs for the 91 sc, no one had them but both places i went had a morotcraft AGSF 34FM it is what came up in the computer and also what came out of the car, is the right plug for my car ? I also bought a set of the app 764 but they look to be around 10mm shorter from the taper to tip and have only half the thread on them will they seat ok.
I have a set of the autolite app103 and they are the same length overall as the app 764 ones. which ones are the best to use the car is bone stock.
athanks for the input
