Campy Threaded Headset

Greetings!

I have lost my manual for my Chorus threaded headset. I went to Campy's web site and downloaded the
only .pdf (dated 1996) they had there for a threaded headset but it does not appear to be for my
headset (their latest model) as it shows cages top and bottom and mine does not have a cage for the
bottom bearings.

Anyone know the bearing sizes (two different ones)? I know, I even have a pair of calipers but I
only want to crack the headset one more time, so how's about a little help here?

As a bonus question: are the bearings in the threadless Chorus headset the same size as the threaded
(backup bike)?

TIA

The replacement bearing sets are the same for both current models and also the same for Record and
Chorus. Lower are 3/16" x 20, same as the classic 1039 headset. The uppper is 5/32 x 22. The older
style set is currently in a yellow package , the new ones are in a grey case.
