This item is used on multiple models.
On 970 and 980 reels ONLY:
This part will serve as a sub for the original 10-970 (discontinued), even though the diameter is slightly larger than the original.
WARNING!!!! DESIGN CHANGE TO BRIDGE/STAR/SLEEVE for 113H-LH reels
******* CHECK THE SLEEVE ON THE BRIDGE FOR ANGLE OF THREADS! *******
RH threading - Right hand threading angles down to the left
LH threading - Left hand threading angles down to the right
Penn changed the angle of the threads so that they only had to manufacture 1 drag star instead of 2 types.
