Working on identifying rust on the floor under the pedal cluster. I cleaned the surface rust off, but have a couple of questions.

On the underside - what is this support for and why does it have a big hole in it?


On the inside it had a circular plug that came out and the area is filled with seam sealer. Should the seam sealer go through to the outside?

Round hole bracket on the under side is for the factory dolly that the 914's sat on. On further investigation it seems I gave the WRONG answer!

Ah looks like the master cylinder hole.

Oh that ... hole!

Thanks, Mark. I need to remove the front portion to make sure there isn't another sheet metal plug on that side that needs welded in place.

Don't cut it off, the car won't run properly without it...

Here is another shot to show I was wrong!

I've cleaned out the sealer on both sides and cut the end off the support piece - now you can see the sheet metal tab. The end of the support piece covered the gap - which was filled with seam sealer. Since it had dried out it was a potential source of moisture. I'll come up with a new piece to weld in & seal this off. It will get undercoating later.



On the inside there's a shelf for the plug. I'll need to cut a new one out of slightly thicker material and weld it in. First will be rust treatment, then weld in a new plug on both sides, then finish off with seam sealer.

Factory feature to allow brake fluid and water to initiate rust.

I had no idea which of those 5 holes you were referring to. Now I see what you have cut off was what I thought was the front tow hook. I've used it a couple of times for just that. Keeps the tow truck guys from latching onto the suspension or torsion bars.

Don't forget that broken gas pedal bolt.
A little heat wrench will have that out in a jiffy.
