[Mgs] B/GT seat back problem - update #2

[S.Carr]

When I said the two toothed plates were "not aligned on precisely the same plane," I meant that—viewed from on edge—they were not directly above one another.  Since the plates can't be kept absolutely tight together—pushing on the adjusting lever moves them slightly (<2 mm) apart at the upper (coil spring) end—there 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 and 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-frame time (hence my next post).  (Yes, we could put the seat back in, position it, take it out again, weld it, put it back in again—but the car isn’t driven in the winter, so we’ll just let it sit until we see if we can find another seat frame.)

Those teeth do seem pronounced, even with some wear.  What is the meshing-half like, although I can't remember what form they take?  If they are not in line are they able to slip past one another, i.e. straightening may help?
 
Is recline adjustment needed i.e. more than one occupant who moves it?  Until a suitable replacement is found could  it be locked in position with a bolt, or even welding, to enable it to be used?
