Part
#100-02U (the "U" indicates a Used Part) is a
combination alternator bar mount and engine lifting
hook for the 3-hole thermostat housing heads. The view
of this part is as if you were looking at the part
from a vantage point above the center of the engine.
Usually only found on engines up to R-10606; although
some had alternator stud in the cylinder head.
Part
#100-03 is an engine hook for the 2-hole
thermostat housing engines. It mounts underneath the
thermostat housing.
Part
#100-04U is an alternator mount for 2-hole
thermostat cars older than 1968. I've also seen these
used as engine hook points so have placed the item on
this page.
Part
#100-05 was designed to be on the rear driver's
side headbolts. Originally the cars came with one
longer headbolt for this spot. Many many people have
put the longer bolt somewhere else without the
bracket; causing a torque wrench to say "it's tight!"
when in fact it hasn't been since the longer bolt
would bottom out in the hole BEFORE pulling the head
tight. Typically I would know this if someone said
their head gasket keeps blowing..."in different
places..." (because the long bolt was continually
moved around).
When
attaching any hook to a stud; remove any other washers
so hook is placed as close as possible to the head or
block. I would consider replacing an exhaust stud
before use as after many years of use they can become
brittle. I would also suggest that even when using an
adjusting bar on an engine lifting device to remove
the valve cover. It's amazing how things can slip and
break a cover. Removing the front grill may save you
some financial pain as well.
