The original kit supplied to me new was supplied with one pack of copper saddles, and then enough ceramic saddles to completely fill the column, As far as I am aware that is how all new T500s came from the box.
Just looked around the net

1.
DISASSEMBLE COLUMN BASE.
Unscrew the bottom flanged bush from the
column.
2.
INSTALL COPPER & CERAMIC SADDLES
Hold the column upside down and add the
copper saddles. Gently shake these into
place at the top of the column. Then add
the ceramic saddles a small handful at a
time. Shake the column gently between
handfuls to settle the saddles in without
gaps. The saddles should fill the column to
within 50mm from the bottom end.
Keep the column upside down while you
move to the next step.
It is important that the saddles are not
loose inside the column. Take time to settle
the saddles in with gentle shaking between
small handfuls.The whole thing can be found here.

very top of the column.
