You may be better off using aftermarket decals in any case, as the ones provided in the kit are extremely basic. In the case of the P47, there is little more than national markings, kill markings (sans swastikas) and side letters. No stencilling, though IIRC, a decal is provided for the instrument panel.
If you do go with the kit decals, I'd recommend a decal bonding agent such as Microscale's Liquid Decal Film or Testors decal bonder as insurance
