I was going to replace the bushes on my throttle shaft, but saw what Eric had
done back in, well, who knows when, and they looked great. So I just stripped
and painted the shaft.

Good catch. They tend to get munged when folks install or remove their engines,
if not as stated heat and time.
I built a cable throttle set up to bypass the Rube Goldberg set up. I have
promised a wrote up to John Sims for quite some time to add to his wonderful
site. I have been slowly working on it and will soon I hope get it to him.

Cross-posting from BCF:
While getting ready to drop the rebuilt engine into my BJ8, I noticed the
'throttle relay shaft'--yeah, the one under the scuttle, all but impossible to
get to with the engine installed--was bent. 'Crap,' I thought, 'one more job to
do before I can get the engine in.' It turns out this was serendipitous--first
time this word's been used on the List?--because as I inspected the shaft, I
noticed that one of the two brackets was also bent, and further inspection
revealed that the bush on the driver's side was way sloppy (actually, pretty
much gone). A quick check of the Moss catalog showed 'N/A' for all the
parts--I'm screwed, I thought. Then, I remembered I'd bought a replacement
set--supposedly made of teflon, but they say 'nylon' on the bag--but had given
up on installing them because the instructions showed 'through BN7 and BT7'
(BJ7/8s need not apply). I called BCS to see what they had, and John, their
parts guy said they'd work on BJ8s. So, I did some digging and, although the
photo of the instructions and applications on Moss' web page showed 'though BN7
and BT7,' if you download the instructions--5 pages!--they've been revised to
show they work on the 'J' cars.
Anyway, if anyone has the engine out of one of the later 6-cyl cars I recommend
you check these brackets and bushings. They are bronze bonded to rubber and,
although my car has nearly 200K miles, I suspect the life of these is
determined as much/more in years as in miles, as the rubber gets baked by
engine heat. The rubber on my driver's side bush was completely dry, caked and
brittle, and could conceivably have resulted in a stuck throttle. The
instructions are intimidating--5 pages!--but, except for having to work under
the dash, which I hate, the job was pretty straightforward. I managed to get
the shaft reasonably straight, and the used bracket I got from BCS was in good
shape (though, in hindsight, I probably could have straightened my bent one),
so now my Rube Goldberg-designed throttle works smooth and with no slop.
Thought I'd pass this along since I hadn't seen this issue discussed before.
I'd long since replaced the rubber/bronze bush on the shaft on the engine, and
should never have to worry about these again. Credit to to Eric Gruden who
designed these bushes, and to Moss for going the extra mile to provide these,
for a reasonable cost (about $13).
