[928uk] Alternator cooling

[Martin Robins via 928uk]

Hi all, I have been investigating a few things and noticed that the
alternator has a cooling duct attached to it. The one one mine is half
collapsed, is there anywhere I can get some duct from?believe it is
70mm. The same material would be good but I guess it doesn't matter.
Also it appears to be open ended behind the wing area,can I assume
this to be right?
Also noticed today - dash lights on when driving, but when you put the
lights on they go out. Don't know if this is normal?
Thanks,
Martin 89gt
