I don’t have the step over my winch post like yours, but I did replace my Fulton winch a year ago. What you will need to do is remove the handle, and then remove the bolts that sandwich the cover on. Once you do that, you can get a wrench on the bolts on the winch frame to the post. Its a bit tedious but not really all that hard. Should take you less than 20 minutes if you are removing and replacing with new. If you are just replacing the strap, you’ll have some additional disassembly to do and it may take slightly longer.
