The piece that Rivendell sells for this purpose can alos be found at most any hardware store for about 25 cents apiece. Also, at the hardware store, you should have a choice of black or white. Anyway, here is the link, so you'll know what they look like. (In the hardware store, look for "Nylon Bushings - 1/4" inner diameter):

One astounding product that Rivendell currently sells is the venerable Pletchser rack. If you have a circa 1960s (or early 1970s) bicycle, and want the most authentic looking luggage carrier, this is the thing to have. Well, there actually were people using nicer racks from British and French sources. But if you were a mere student in those days - and spending your own money - you used the Pletchser, since the American Youth Hostels offices sold it for about 3 dollars.
(Parenthetic note: In the '60s, I actually did see Herse and Singer touring bikes, properly kitted out with decent racks - not to mention fenders and even triple cranksets. But these were all being ridden by people who were contemporaries of my parents, with incomes far exceding the wages I earned at my after school job.)

\r?\n> ''hello,
\r?\n>
\r?\n> I recently purchased a condor frame and fork that someone
\r?\n> drilled to
\r?\n> take recessed-mount brakes.
\r?\n>
\r?\n> Does anyone know of an off-the-shelf bushing to take up the
\r?\n> slack
\r?\n> between the brake bolt and the enlarged hole so i can use
\r?\n> nutted brakes
\r?\n> on this frame?
\r?\n>
\r?\n> or is there some other way of dealing with this?
\r?\n>

\r?\n> Rivendell sells a plastic sleeve to fill a recessed brake
\r?\n> frame hole so
\r?\n> a normal nutted brake can be used. It tended to compress on
\r?\n> me and the
\r?\n> brake would loosen just a very little.But it worked OK but
\r?\n> hard to
\r?\n> center brakes pads on rim.
\r?\n> I used what next? Oh yes I got a SS lock washer that fit in
\r?\n> the recessed
\r?\n> hole and brake bolt could go thru. Most SS lock washers
\r?\n> have an outer
\r?\n> diameter same has bolt head for a recessed bolt which is
\r?\n> the diameter of
\r?\n> the recessed hole. One can just use a washer that is bigger
\r?\n> in diameter
\r?\n> than the recessed hole. However I found some play in brake
\r?\n> which no
\r?\n> matter how hard I tighten was still there.
