Chris,
Been there, done that.
My wife's V12 equipped 1990 XJ-S convertible had one throttle
linkage bushing missing and the other one was cracked when I purchased
the car. I reviewed Kirby’s book and other suggestions on how to
improve on the design, but decided to replace with the original
specification bushings.
I did this task along with a lot of other engine work
(compression check, new plugs, new rotor, new wires, new cap, new fuel
hoses, fuel injectors cleaned, etc) so I don’t recall it being a
particularly difficult or time consuming task. Nor do I recall needing
any special tools.
As I remember, I disconnected the linkage clips, the throttle
lever set screw and the mounting bracket at the rear of the manifolds
and maneuvered the shaft clear enough so that I could remove and replace
the bushings. You may have to disconnect the AAV hose on the left side
as well, but I think I did that at the same time.
I highly recommend getting a digital camera and taking lots of
before, in between and after photos of projects like this to make sure
you get everything back together again. Also put clean towel underneath
the entire area to make sure you don’t lose and critical parts.

To clarify:
I am referring to part # C34388, which is a black double-
lipped nylon bushing which fits into part # EBC3624
(''Throttle linkage bracket-LH( which is of course bolted to
the back of the inlet manifold.
It looks like I should be able to slide the bushing on the
linkage shaft from the back and then squeeze the front lip
of the bushing through the opening in the throttle linkage
bracket.
However, Kirby Palm lists several different methods, all
involving removing lots of tiny pieces.
