All of my Shake Heads that come with a Screw Lock, now have centering pins to help make it a little easier to rig all of your soft plastics. Can buy them in 5 packs, 10 packs or bulk 20 packs directly off my web site. Not sure you can get them like this any where. I sell 3 different types so I should have something there that will fit your needs. As always, feel free to give me a shout if there is anything that you need or that I can help with.
Thanks and below are links to each of the 3 shake heads I am referring to. https://www.flatlandscustomtackle.com/store/p12/Screw_Lock_Shake_Head.htmlhttps://www.flatlandscustomtackle.com/store/p10/Pro_Football_Shake_Head.htmlhttps://www.flatlandscustomtackle.com/store/p69/Ledge_Monster.html
