[V8] Reference sensor R/R HELP!

And Keith wrote this a several moons ago:

color of the grommets.

involves a lift and an air impact so I will leave the actual procedure
alone. Both sensors are mounted in the same fixture on the left side of
the block behind the exhaust header. There is a head shield that is part
of the assembly. Two 10mm bolts hold everything together, remove these
and the whole assembly pops right out. The connectors are under the left
distributor.

I (dave) would just add that I've done this procedure on two different
cars, both manual trans, and one was done by just jacking the car up a
bit and turning but not removing the wheel.   Take out the distributor
and cruise control assembly.  A friend is probably the biggest help,
because the two 10mm referenced above are difficult to reinsert without
someone to say, "ok, up a little, now over, no, the other way...".

If there's a ton of gook, try to degrease the area a bit first.
