Mystery Holes in Firewall 23rd Series

Posted by JD in KC On 2010/4/30 11:23:30

I recently removed the old carpeting from my '50 Custom in preparation for installing new carpeting and seat belts. I found these two holes in the firewall. I've looked at all the plates in the parts manual and can't find any reference to them. Are they factory placed or did the former owner do yet something else inexplicable to the car?

I can't imagine what they would be used for except for possibly an attempt at some point to install aftermarket air conditioning; but there is not the slightest trace under the hood that this was ever the case.

Anybody know what these are?
