When ordering Shimano parts the part number needs to be in SEVEN digit format. Most of the correct part numbers are listed at the bottom of the page on the schematic. You would need to scroll down to see the correct part number. On spinning reels the correct prefix is RD and a space (example: RD 0795). On baitcast reels the correct prefix is BNT with no space (example BNT1207). On the larger saltwater models the correct prefix can be TT, TGT or TLD. This is listed on the individual schematic for the model you have. If you have any questions CONTACT US.
