As i'm working on these
for my Celica, I thought i will put together a specific 'how-to' for
future reference.
Cutting away the polycap housing is the first step, which is not easy
without some sort of motor tool. A steel cutter is used for the job by
steadily grinding away with the tip. Take it easy here and watch out for
the cutter biting into the plastic, when this happens it will jolt and
will usually damage a spoke. You will notice a small recess when the
housing is removed, this is what will be used to fit the peg into.
The pegs can be taken from a Fujimi kit but chances are
you won't have any, so we'll make some. 2mm styrene rod is what i'm
using for this, 2mm seems to be the standard for the pegs on most rims.
The recess on the rims has a larger diameter than 2mm so
you will need to widden one end of your peg to get a tight fit. By far
the easiest way of doing this is to use heat and soften the tip, then
press the rod onto a hard flat surface. Try to keep it as straight as
possible, you could from some kind of jig but dont worry coz you can
always sand the base flat. 

Sizing
the base is a job for the Dremel again, fit the peg straight into the
chuck of the drill and use a sanding block or file. Apply light pressure
and check the fitment to the rim regularly coz you want this to be a
very tight fit. In the case of this how-to, i'm using 17" rims
which have a smaller recess than the 18"s, so the base on these
pegs is barely noticeable but necessary all the same. 

Use
your choice of glue to attach the pegs, i've gone for styrene adhesive
coz this will weld the join together and should provide a stronger bond
than CA coz of the small area we're dealing with. Either way these are
still fragile so fitting and removing them to their hubs should be kept
to a minimum. If you have followed everything so far by keeping a tight
fit and a flat base, the pegs should stand at 90degrees and u won't have
wonky rims. This is infact another reason why strene adhesive is better
here, coz u will have time to play with the allignment.
Do this 3 more times, cut the pegs to length and you're done. 

Hope
u all find this useful.
