Don't be a-fearin' muh friend
None of that linkage cleaning/sanding/lubricating/adjusting will cost you a red cent.
If you really have no way of jacking it up safely you can do it all from the driver's side with long arms and a mirror (though it'd be a whole lot easier if it were jacked up.
The kickdown linkage is so simple it's child's play and requires only a 1/2" wrench and a little trial and error.
First though, you want to make sure it even needs adjustment. More likely it's just rusted itself together with the stud it rides on.
Consult your factory service manual or pictures from it, here on this site, and get the wire brush, sandpaper and grease or anti-seize out.
All you need are needle nose pliers and a 1/2" wrench to remove the linkage pins and bolt. Heck you might get lucky and get it all moving without even removing it and just spraying some penetrating oil and working it all with your hands.
NEVER forget the upper linkage spring, at the back of the engine either. If it that ain't there, that can lead to a lot of what you're describing !
