For some reason my CMC did not come with the little round squishable vents (probably still on backorder). Over years I have tried various ideas - like long straight yota PU vents and even VW bug vents. One too long and other too short. After looking decided to got with the OEM Speedster vent grille (hence why my build has taken a millennium). Other than the fact to conform to windshield the need to go in far corners - the look is spot on. So not how to feed the luke warm air to them. The yota vent tubes were right length - but straight. So made wood mold of the vent grills and tacked yota plastic to them to make a mold with curved shape. Yota tubes came apart so I had 2 sides of one separate. The final product is pictured below. Just need to mix some gorilla hair up and bond to dash. (You can see where the old straight yota ones "were" in photos --- right where tonneau snaps should go!)
Should have taken photo of the molds - Shubbie has them for his build.
