The Tiger's radiators each had two feet, fixed from below by two large bolts.
The outer leg of each radiator sat on the floor of a side sponson. To conceal the bolt heads, the floor of each sponson had two round holes (covered by a welded panel inside the tank).
Takom's sponson floor has no holes. You can improve the kit's accuracy by drilling them, and putting bolt heads inside them. Align them with the radiator on the inside of the model.
