                                                                                                                            372TI014 KN

                                                                      .   Attach padding to back plate via press studs

.    Remove hip belt from back plate

                                                                                                                            372TI015 KN
.    Drill holes (dia. 6 mm / dia. .236‘‘ or 15/64‘‘)
