B&S 25hp twin plastic manifold replacement with metal?

[boggie]

Has anyone replaced a plastic manifold with a metal one? If so what was used, as the metal one I found was shorter. Make a spacer???

I have tried doing this a couple times and unfortunately i have not been able to get it succesful. Those damn plastic ones warp like crazy and power distributors shows them on back order.
