I usually go to Thorne Brothers in Fridley. They have a great staff of guys who build and repair rods. I do my own repairs and when I can’t get it done I go to them. You more than likely will have to strip the epoxy and threads off and retie a new guide on. It is very frustrating and time consuming to take guides off of factory made rods, and you have to be extremely careful of the rod finish.
It can be very hard to match the quality of your finish to the rest of the rod.
Good luck and I hope this helps point you in the right direction. I think there is a guy in Rochester that builds custom rods and he may do repairs too. Sorry don’t have a clue wha this name is, I think Briank has gotten a rod or two from him.
