Holes in floor and trunk

[topknot]

I’ve seen a picture of a bare firewall with text saying what all the holes are for. Is there anything similar for the trunk and floor? I get some of these may be for drains but what are all of these holes for?

Most of them get Body Plugs. Also holes for the seats. In the trunk you will also have body plugs, and holes where the rear tailpipe hangers go...

yes I am aware most get plugs. My question is why are they there? Is it to access something under the car? On the floor there's 17 holes that don't seem to have a use, obviously this excludes the holes needed to mount the seats.

When the cars were built at the factory, they were dipped in different chemicals at different intervals. They are present there to drain whatever product they used at the time. Bonus...Bonus...Bonus for us car owners. If you have rain or water issues, it provides a very nice drain outlet.....

The bulk of the holes with rubber, or sometimes plastic or metal, plugs are for drainage of the cleaning, treatment, and primer solutions used in the unibody dip processes used when the cars were constructed as described in the following image:

Some of them may have been jig alignment holes used by the factory welders/ chassis construction workers.
