3.7 Riser Shortage

[NorthernNeckV-20]

So has anyone had to replace a riser recently on a 3.7? Can't find one anywhere, all three manufacturers are on back order with no projected ship date in sight. I checked everywhere, mine has an alum manifold and seems to be the hardest to come by. Didn't know if anyone else is having or has had issues with the availably of risers. I am even considering engineering something and dumping the discharge RW further down from the riser on the rubber hose. My only concern would be keeping the contact point between the riser(which is dry) and the rubber hose cool as this was the original intent of the design. Thoughts, ideas, concerns.

165hp RWC, just FYI.
