Yes, the reel seat problem can be fixed.
First off, is the rod worth fixing? How much are you willing to pay to have it fixed?
Take the rod to your local B&T shop and ask if they will fix it and how much? Also ask HOW will they fix it.
Worst case you can line up the reel seat with the guides, tape it in place, drill straight thru and install nuts and bolts. Not fancy but do able.
Other options I would use.
Cut off the rear grip. Slide off reel seat and install a new seat. Replace rear grip and butt cap.
Hacksaw on an angle thru the reel seat and blank. Install new reel seat on top or bottom part of blank. Epoxy and let dry 2 days. They epoxy other part into the reel seat. Because the cut was on an angle the parts will line up.
My guess for labor would be around $25 plus parts.
Lets us know what you decide and how it works out.
