..... I keep a 1/16th drill bit handy on my workbench, you'll need it to open up some required blind holes depending on the build options selected. I run the bit into each hole I'm going to use both before and after paint to make sure they are clear, you find that the assembly will go more smoothly. The chassis to body fit is probably the most challenging part. I use tapered toothpicks for temporary spreaders as needed.
