I haven't heard of fitment issues with the new castings. I have sold over 100 of them by now. I still have the VF40 housings if you request them, but from now on out it will be new.
As for install hardware: Studs, water lines, banjo bolts, drain tubes, turbine inlet and outlet gaskets, they are in the make. I still haven't recieved them. Once they do, the prices will go up about $50.
