There are two large holes in the base of the firewall, near the subframe connector . One on each side. What are they for? In the late 70's I blocked them off hoping the temperature of air flowing into interior would go down, and it seemed to work particularly they air from the kick panels.
isn't that the only access to the subframe attaching bolts/bushings? can't quite remember without looking at mine.
Off the top of my head, that's what I was thinking too.
I used to be indecisive. Now I'm not sure. I feel like I am diagonally parked in a parallel universe. 1968 400 convertible (Scarlet) 1976 T/A - 455 LE (No Burt) 1976 T/A New baby, starting full restoration. 1968 350 - 4 speed 'vert - 400 clone (the Beast!) 1968 350 convertible - Wife's car now- 400 clone (Aleutian Blue) (Blue Angel) 2008 Durango - DD 2008 GXP - New one from NH is AWESOME! 2017 Durango Citadel - Modern is nice!

I thought the "toe boards" for the floor pans are behind there so there is no opening to the car interior.

X5, but I recall they are not really exposes as the subframe turns upward at that point and I think the inner fender well brackets block it sort of also? going on memory here also.
The bolts come up from the bottom and the nut is caged so it couldn't be for attaching the body mount, unless to replace the caged nut. My guess is they are there to catch dropped washers or tools ,which rattle under there, and in turn cause the owner to search for hours to find only to be discovered forty years later by the fifth owner who couldn't hear the rattle as he's half deaf. In my case it was a screwdriver which I still have if the original owner is still looking.
