Aftermarket service manuals are available at a number of places on the net,NAPA auto parts,and sometimes the library.I don`t have info on plug gap but if you set it temporarily at .035 You should be fine until you find the correct specs.
You should get the proper year before getting a manual.Model number should appear on the top of the mounting bracket.
