Twin 90 Rigger Cowling - "curved"

[Shane Bastick]

Does anyone know of a twin 90 sized rigger cowl, that curves a little towards the front to suit tubs that curve down more gradual, I have a SGX cowl, but offcourse with the SGX style tub the curve on the tub is only at the very end. approx width of the cowl needs to be 172mm

thanks
