What is this and how do I get one...

[trunt]

I'm bored awaiting my final piece of bodywork so was eyeing up my firewall and wondering just what all the holes are for..

So one that has foxed me is circled in red, I have a slot and a hole there .. what is it? I definitely don't have it..

(Apologies to whomever owns this pic! -- i found it on a google but it shows it nicely)

It’s the drain to prevent the heater plenum filling with rainwater.
Rubber flap is hinged at the top and acts as a valve to allow water out but stops fumes getting Ito heater.
Rivitted metal plate compresses foam to stop water running behind it.

The rubber cross section is quite complicated. At the top it has an arrowhead cross section which goes into the slit above the hole. At this point the rubber is relatively thin (allowing it to act as a hinge like John says) so, if you turn one up on a scrapper, don't just try to pull it out of the slit or it will tear.

Never seen them for sale, but the few scrappers I've looked at all had the rubber still in place. Maybe Tony White on this Forum (Trader)?

Thanks! I just could not see that on the parts list nor in Rimmers. Knowing it’s also from a spitfire helps. I’ll ask my mate, he may even have one in stock..
