John Runberg and I have been working on a reproduction a/c type heater duct. a/c model FJ40's use a unique (the "L200") heat duct that allows more clearance for the evap case. It also allows more leg clearance for the passenger as well if used on a non a/c model. If you look at ccot's reproduction OEM type heater they issue a dryer duct for this one. Brett Galand has tried to cut down regular ducts with little success. The vacuum formed duct John's company would churn out is a great solution for this piece -the single rarest part to a factory nippondenso ac system. ...anyway...if we can get a group buy in for 50 or more, costs would be under $50 each. Please PM me if you are wanting a duct or need more details (or post here).
