Pre perego 4.35

I currently have a valco stroller (second hand gift from my sister who him trilled about!!) and am wanting to get a pre perego 4.35 however I am having a heck of a time findin an adaptor that will let me use both together. Does anyone know where I can order one or if it exists! I've been googling my fingers off all night and I may have found one but I'm not sure if it's actually for the 4.35. Can anyone help!
