Dave, the screw on the washer bottle is typical for an electric pump style washer bottle. The two screws are the same for the foot pump model. I have parted out over 300 A-Bodies in my time, and have found TONS of stuff under carpets! One 69 GTS I took the interior out of had over 100 of the small rubber door plugs under the carpet in red and green! The assembly line clown must have knocked over a can of them and just put the carpet down over them instead of cleaning up his mess. That has to be the most optioned-out 4-door 70-72 Valiant I have ever seen!
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
