I'm guessing by "NLA" you're meaning from VW,
I did leave that out. You can source that from your local auto parts store. The hose is 5/8" heater hose from the rear heater T all the way to the front. Then there are two preformed hoses at the front heater core which we have in stock. Here are links to them: http://www.vanagain.com/shop/front-heater-core-hose-feed-vanagon/ http://www.vanagain.com/shop/front-heater-core-hose-return-vanagon/ They are $45 each. Let me know if we can help you further.
I think you left out the hoses that run from the rear heater core to the front heater core and back again. see Bentley 19.10 I am looking for a replacement of these hoses as the ones I have were implemented backwards by the PO and result in warm air contantly flowing onto my feet.

Actually it means "No Longer Available". If you see a hose listed like this email me and I may be able to get you something that is comparable. It won't be exact, but it will work. Ken
