If the rod blank and reel seat are ok, I would get new guides. Sorry but no idea who might do this for you locally.
My first rod build was an old Ryobi 2 piece fly rod I bought from BA, the reel seat was loose, guides were corroded a bit.
So, I stripped it back to the blank, made some jigs and rebuilt it as a SWF rod.
It has even caught some Kahawai! Picture at Ninepin, BOI.
