I took the two stock rear rod holders off my 2004 GW 228 Seafarer but I believe those are 30° angled rod holders, if I’m not mistaken? I’d give them to you, or any other member on here, for free that needed them and paid for whatever the shipping costs might be. Although the shipping costs, depending on your location wouldn’t probably be justifiable considering that you can find nice 15° angled rod holders for $60 a piece, or less online. Good luck!
This stainless steel rod holder provides a 15 degree angle to keep your rods in place. It also has a removable drain plug and slots for all sizes of rods.
