Another alternative is 1.25" stainless steel tubing mandrel bent at a muffler shop. Otterstat bung and coolant expansion tee would have to be welded on. Instead of hose barbs would probably end up with flared or expanded ends -- equally effective seal. Advantage would be ability to replace multiple factory sections with contiguous pipe, especially eliminating junction under closing plate.

Is there a tool or sandblasting system you can buy retail to do this yourself? As part of our ongoing restorations of these cars it would be nice to clean and sandblast parts as we need to make repairs... > > Mike C
