I'm looking to go ahead and notch my frame. I'm not ready to go cutting up the bed anytime soon, so I just want to do a frame notch and not a step notch or bridge ... I hope to eventually run the KPComponents 4-link Cantilever if that makes a difference in what notch to get now. Whats a good bolt on one to get, the suicidedoors.com ones? anyone else? thanks.
