When I was ordering the parts for this kit I picked up the .10uf but I haven't seen where the it is supposed to be placed in the crossover.
You need two .1uf caps in tweeter circuit, see schematics in left column of the link page. Place one parallel to 6.8uf and other parallel to 2.7uf and inductor. There is also a pic of the crossover.
