Since your spindle is 1-1/16" where the outer bearing rides you will need the # L44649 as the correct replacement.

It is a good idea to go ahead and check the inner bearings, but since you mentioned your spindle is tapered you will need to look for the bearing number stamped on the face of the inner bearings as shown in the included picture of the # L44649. Based on the information I could find on the Dexter 8-258 you should have a straight spindle that uses # L44649 as both the inner and outer bearing.

If you can let me know the bearing number of your inner bearing I would be happy to recommend a replacement.
