Hi Ed,
That mystery bolt sounds like the remains of the upper bump stop from the
front suspension, after the rubber "cone" has completely crumbled away from
age. Time for a replacement. The originals had drillings for cotter pins. The
replacements generally just use nylock nuts. The bump stop doubles as one of
the
spring pan mounting bolts, the middle one in fact, on the rear lower control
arm.
Hi Tom,
The Torque Reaction arm limits the amoung of twist the engine can
physically do when the accelerator is pressed. This helps the motor mounts last
longer
and avoid damage to the coolant hoses, fuel lines, u-joints, exhaust system,
etc. that might be overstressed by excessive movement of the engine.
Note, the arm bolts to the bottom of the front mounting plate, and has a
rubber capped adjusting nut threaded into it and trapped in place with a
locking nut. The rubber cap is what actually pushes against the frame rail to
limit
engine twist. The adjuster needs to be backed off when the engine is lifted
out of the car, but it's easier to just unbolt the whole torque arm and remove
it, which is probably why so many end up lost (Gee, I wonder where this
left-over part goes? Oh well, what-the-heck! It's running!)
Cheers!

I am very reluctant to ask the list to identify a bolt, however, this is
a very unique bolt.
3/8 UNF X 2" long, has a smooth rounded head (carriage bolt?), has a
large (fender washer size), thick (3/16") washer welded to the head, and
has a hole in the end for a cotter pin. Mine had a nyloc nut on it.
