I tried looking this up in Clymers and found this
to be infinitely easier to understand.
To do this the only things you need are:
1. A phillips screwdriver (+) -small
2. A 8
mm key
3. Two hands
4. Two 3.4 Watt fresh bulbs (SN 09471-12028), the bulb 09471-12082 might do it too.
Steps:
a) With your hands unscrew both the Speedo and the Tach cables from the back of your clocks,
they might be tight right now but you don't really need any tool.
b) With the phillips screwdriver unscrew the Reset Knob's little screw (only for Speedo),
which goes far inside the Knob.
c) With the 8 mm key unscrew the 2 nuts on the back of each clock (total 4) and save the
washers and rubber.
d) Pull out the clocks and the bulb cable will show off, gently pull back the bulb cable,
it comes out with the bulb, and pull out the bulb.
e) Proceed backwards to reassemble.
You don't need to disassemble the dash silver cover; keep it simple.
