Pesky demister vent outlet orientation

[bloodknock]

Hello again brothers in suffering
I wish i'd had a digital camerawhen i stripped this beast in the seventies and eighties......i continue to wrangle with the heater and its associated tubes!
Having finally got the heater unit pretty solidly and accurately installed, this time its the demister vents that are causing me angst.
See the photos, the vent diffusers that allow air through the dash crash pad can be installed a variety of ways. Having browsed various photos, I'm not sure whether the hose coupling end should be biased forewards or backwards. Its just as easy to install either way around. (and I have!) Currently theyre biased towards the interior, and this appears to give reasonable access to the water feed couplings, and make fitting the air feed pipes easier.
However, when did Lotus ever consider ease of installation?! and im worried that they may have been biased the other way towards the engine bay (?dash clearance considerations?)
Again I ask for anyone who may have access to an original unmolested sprint and can get access to or remember this feature to please advise.
Thanks
Bob

I think that this is correct, it seems to work and satisfy the needs of pipe routing:

Bob, I think you are correct, it looks very similar to my set up:

Have you checked your heater fan motor is functional before you start to put the dash back?
