The tang has a front edge, side faces with apertures therethrough, a top seat, a rear seat and a bottom seat. The boot tip has a front wall seated on the tang front edge and a right side wall seated on the shear side tang face, rear seat and the top seat. A bottom wall of the boot tip is seated on the tang bottom seat and rear seat forming a shear punching edge between the front wall and the bottom wall. An access plate is seated on the guide side tang face, the top seat and the rear seat. The boot tip right side and access plate have matching apertures therethrough and alignable with the tang apertures to secure the boot and access plate to the tang for protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess. One or more shims are provided and insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force.
