Making it compatible with 2.0 is quite simple.
first base game version needs to be updated:
"factorio_version": "2.0",
then in file prototypes\vtk-armor-plating-player-tank.lua needs these rows:
        vtkplayertankrecipe.normal.result = "player-tank";
        vtkplayertankrecipe.expensive.result = "player-tank";
be replaced by this row:
        vtkplayertankrecipe.place_result = "player-tank";
and in file prototypes\vtk-armor-plating-items.lua old crafting recipe definitions:
        ingredients =
        {
          {"steel-plate", 10},
          {"iron-plate", 5},
          {"plastic-bar", 1},
        },
        result = "vtk-armor-plating"
need to be replaced with new format:
        ingredients =
        {
          {amount = 10, name = "steel-plate", type = "item"},
          {amount = 5, name = "iron-plate", type = "item"},
          {amount = 1, name = "plastic-bar", type = "item"},
        },
        results = 
        {
          {amount = 1, name = "vtk-armor-plating", type = "item"},
        }
for all three recipes.
