When I got the COPO Chevelle documented through George Zepora at Vintage Vehicle Services in Canada in 1999.On the title page with all the codes deciphered it states:
201 1969 Chevelles(Same model no.) exported from U.S.,no breakdown of COPO production.I would not venture to guesstimate on COPO production outside of Yenko.Noone seems to agree on this number.
