I am redoing the main pipe section (once I can find some) but I wanted
that end of the pipe clear so my windshield could slip over it... Hmm
perhaps this is why I am getting knocking of the nt4 capsules on the
windshield - due to my lower mount point for the elastics...

It looks like thicker pvc than the pipe I have. With the pipe I am
using I have actually considering glueing a second layer of pvc on the
bottom of the main pvc section to provide more strength...
