I'm trying to attach a Manfrotto LANC pan handle (https://www.manfrotto.us/pan-bar-rem...cameras-w-lanc) to an Ikan fluid head (https://ikancorp.com/shop/camera-sup...-head-e-image/).

Unfortunately the Manfrotto handle is about 1-2mm larger in diameter than the Ikan handle and doesn't fit neatly through the rosette mount. (I can squeeze it through but then the screw doesn't meet the other side of the mount sufficiently to attach it.

Are there any options people are aware of to mix support accessories? The Ikan rosette screw is 75mm and the teeth 300mm.
