EC250 exhaust O rings?

[BIG TOOL]

Hi Guys, I was looking at the parts crossover list to see what O rings to get for my exhaust spigot, but all it said was " late model CR250 " Well I couldn't decide if that meant the '92-'01 or the '02-07 Cr250 or will either style work? I'd appreciate it if anyone could set me straight about this...
Thanks!

'92 - '01, or buy in bulk from an o-ring supplier. 44mm x 3mm Buna N. Viton is better but more $$.

I was at the corner store here in the woods of VT and, much to my suprise, they have an assortment box of Buna N for $.50 ea.
The sizes weren't listed though. Just a single # like 20 or 30. I googled but didn't find any reference like that. Any clue ?
Maybe I need to look at the box better or just grab a couple and try 'em.

Those are standard sizes, not metric.

Was the, (44mm) X 3mm, an I.D. Internal Diameter or O.D. Outside diameter?
I could take my pipe off and measure one, but, I am feeling lazy today.
