Hi -
I have some of the zane front tubing available if you are still interested. These are OEM tubes. Send me your email address and I will send pics if you want.
If you want to get brand new you can order it from airtech, link is http://www.airtech-streamlining.com/miscpages/foam.htm, scroll down the page and you will see the airtubes
Note: When you speak to them you will want to specify a 1.75 inch tube.
Only problem with airtech is they can take a while to ship. I placed an order with them that got buried somewhere in their system, took about 4 weeks
Cheers
