I have a 73 with a new hood ( no holes yet ) and I want to mount a set of NOS 340 four barrel emblems in the original locations on the side of the scoops. I have the dimensions for the hole locations, but I don't know what size the stock holes are . Also, the new emblems have a plastic sleeve on the mounting pins. Are these what hold them on, or is there speednuts on them ? Thanks, Mike Hi Chryco, the car is getting better all the time.
