When we started pulling the car apart I was concerned about the fact there was two inches of water in the cowl near the center drain 'cause it was plugged. And there was some surface rust after I had drained it. After we removed it (cut it off) we blasted the top of the firewall and the underside of the cowl.
Here is a list of things found once I cut the cowl off.
1. Underside is unpainted and they used galvanizing to protect it. After
30 years covered in surface rust.
2. After sandblasting a couple of small pinholes around the bases of the
airboxes. (If your floors are wet could be this, fortunately mine
weren't)
3. Center drain is very narrow and easily plugged by debis. Center
drain is metal at the top encapsulated with rubber. By dumb luck I
found one on Ebay while working on it. If you remove the plastic
screens you will find it near the wiper motor.
