Those teeth do seem pronounced, even with some wear.  What is the =

  Yesterday we partially dismantled the driver=E2=80=99s seat back on my =
=E2=80=9971 B/GT to see why it would collapse backward with even =
moderate pressure.  Alas the problem is not the same or as simple as =
Paul Hunt's=E2=80=94although a previous owner clearly had the same =
problem as Paul, since the same pin was crudely tack-welded in place on =
my car!      Possibly from 50 years of failure to pull the adjuster =
lever far enough before pushing the seat backward to disengage the =
teeth, both sets of teeth are worn=E2=80=94and they're also not aligned =
on precisely the same plane, so they're worn at an angle.           =20

When I said the two toothed plates were "not aligned on precisely the same =
plane," I meant that=E2=80=94viewed from on edge=E2=80=94they were not dire=
ctly above one another.  Since the plates can't be kept absolutely tight to=
gether=E2=80=94pushing on the adjusting lever moves them slightly (<2 mm) a=
part at the upper (coil spring) end=E2=80=94there is only about half-width =
contact of the teeth, and one side of the tip of each tooth is worn away at=
 such an angle that the plates slide away from each other under pressure an=
d the teeth won't stay in mesh.  We don't see any reasonable way of getting=
 the teeth re-cut to square the tips off, so it's look-for-another-seat-fra=
me time (hence my next post).  (Yes, we could put the seat back in, positio=
n it, take it out again, weld it, put it back in again=E2=80=94but the car =
isn=E2=80=99t driven in the winter, so we=E2=80=99ll just let it sit until =
we see if we can find another seat frame.)
