Correct, and a couple of things I might add. Use neverseez on the
bolts when you put the seats back in.
On older cars, the seat rails had steel rollers with orings around
them. These orings dry out and rot, then the seat slides a little
bit and binds. If my memory is correct, the 123 and 126 also have
these rollers. On one car, I took the slide apart and removed the
rollers, rather than buy new slides. It is something to be aware of.
I would of tried putting new orings on, but I was not sure how to
position the rollers for reassembly to get full movement. The slide
is still working now, without rollers. I have never had to do this
to a 123 or newer. However the age of the 123 and early 126 cars is
such that this may become a problem of this sort. So far, I have
been able to clean and lube 123, 124 and 126 seats and put them back
in.
I agree with Hendrick. On my old 79 300TD the rails were hopelessly jammed
with dirt and rust and mystery stuff (soda pop?). I took the seats out,
removed the rails, and washed them thoroughly with soapy water and a brush.
After drying I greased them and reassembled the seats. The rails still
looked like crap because of surface rust but they worked like new. Do this
on a warm day and use some cardboard or a rug to rest the seats on (upside
down) while you disassemble the rails. Also, if you have the right size
taps, chase out the threads where the seat screws to the floor to make
reinstallation smoother.

To really fix a MB slide rail you need to take the seat out and
disassemble the rails, clean them and put some grease in there.

I'd guess that your problem is in the height adjustment - probably need
to get it into the all-the-way-up (i.e. forward most) position.
In other words, there are TWO front-to-back seat adjustments on a W123
driver's seat: one in the front, corresponding to that on the passenger
side, and one on the side. The one on the side, because the way its
tracks are inclined, affects the height of the seat more than the one in
the front does.
