Parts needed for r2 restoration

I am in desperate need of some parts to continue on my 1940 R2 / serial 6J869 restoration. I know a few of these parts like the manifolds and carrier rollers might be hard to locate new obviously but i am hoping someone could let go of some decent take offs. The machine has been gone through mechanically and is currently getting ready to be sandblasted so these parts would go a long way to finishing it up. Any help would be greatly appreciated..:help:
