I finally got my Decal mojo working and did a better job than I thought I could ( my least favorite part of modeling )
Used a thin piece of painters tape in line with the top of where the numbers are to define the herald area and placed the herald,
then placed it on the other side of that line ( as in the photo ) and cut the tops of the numbers flush with the edge so I could slide
it up to the painters tape to align them vertically.
Hope the other side comes out as well. FYI the decal sets are for the green Jersey Central "Passenger Equipped Online
Service" express boxcars - HO scale for the heralds and O scale for the numbers
