There has been other discussion about these hoses in other threads. To my knowledge, nobody at this time reroduces similar hoses.
You might give WCCC a call since Cougars also use this option. I believe they have somebody who was making headlight vacuum hoses with correct markings and was considering making hoses for the Tilt Wheel cars too. One of the problems it seems is that there were early and late versions and to my understanding, since the hoses are basically cut to fit to help keep costs down, nobody has a sort of chart with what length of what color for what month of production. Also, a VERY limited target audience for such a huge investment of inventory.
There, that should be as accurate of my current understanding
