Default restrictor pill size

Anyone know what size (And where to get) the restrictor pill for a 95 STI ?

my dyno run earlier in the month brought to light that my restrictor pill may be missing (Thanks Silver for the advice) as the car wouldnt rev over 5500rpm.

The pipe it goes in was original so I didnt give it a second thought and got new cam and crank sensors (The other two possible causes I was given).
Anyway, turns out the pill is missing after all! The engine and ECU are from a 95 STI-RA. I have seen various sizes given when searching the net so I figured it would be best to ask someone who knows rather than risk misunderstanding something.
