3B rear caliper guide pins

So, the story goes these guys aren't available separately, right?

Has anyone checked to see if they're the same size as any other
girling caliper guide pins?

I show them to be -exactly- 8.4mm according to my micrometer; I can
provide more measurements of the one I have sitting here on the
desk(with a lovely little notch I can't seem to sand out.)  Other one
looks to be bent, possibly.  That explains the uneven braking I get
all the time from the back end, and the "sticking" caliper chewing
away at the pads+rotors.

Girling/Lucas made a ton of calipers and these calipers had to have
been used on at least a few other cars, right?

I can't believe that they can't be sourced through one of the following:

a)some other marque's parts counter(ie, maybe some random Volvo uses
the same rear caliper, for example, and you -can- get them from Volvo
b)maybe the pin is the same on a caliper which Audi does list the
guide pins for separately(as mentioned above)
c)hiring a machine shop to make a bunch(obviously not practical save
for a pretty large run of 'em)

Any ideas?

Noticed on both the brackets and the calipers that a rather large
area had been heavily ground down, and it was obviously some sort of
part number or logo, because it was next to an untouched # or logo in
the casting.  Makes you wonder what was there, doesn't it?  Maybe a
Volvo logo, and the "Volvo" calipers have the VW/Audi logo ground
off? :-)

Oh, and I saw something cute today, on the back of a Volvo wagon in
town...license plate "OV LOV"  First time I've actually seen a volvo
with that as a plate.
