Question About AutoLight plugs APP 765 VS APP105

[garync1]

OK on another post I resolved my bump shudder issue.. Come to find out it was my plugs.. I did go with Auto light App 765 the first time.. Also re gaped them because the gap was not correct when I used the coin type gap set. So now I only use the wire type.. Which most mechanics have said all along. Hey I lost my pack set so i used what I had.. But now I have the other wire type disk set so bye bye coin set.. Any way.. Using the APP 765 are double platinum but there is one issue.. There threaded short.. The APP 105 are full threaded.. Auto light even explains this on there web site saying there the same plug..

My issue is how would they not set deeper.. There picture shows it should not but I think thats hog wash. So When you change your motorcraft take a look at if they are full thread or half thread..The APP 105 are full threaded and now my bump shudder is gone and my fuel millage has went back up..

My question is is anyone using the APP 765.??? Are you having issues??
