I recently ordered a medium Mohr bobcat jawset. Numbers on the top and bottom jaw read JNT007 & JBT007. The tongue reads MED Bobcat. I have tried test fitting this jawset multiple times and the tongue seems too big/wide in the back to fit flush down into the jawset. The "wings" on the back of the tongue are so wide the tongue sits real high with a large gap between the bottom of the tongue and the floor of the jawset. What am I doing wrong? Thanks.
