FYI, I have built a Peugeot UO-8 model data matrix, similar to the ones on the Retro Raleigh website that provide specific component/configuration information by year. Have UO-8 data from c.1970, 1973, c.1973/74, 1974, c.1977, Late 1970s, and c.1981 (sources include a half dozen Peugeot catalogs plus The Complete Buyer's Guide to Bicycles [1973]).
Have forwarded a copy to Dale for CR's Peugeot webpage. In the meantime, if your interested, email me and I'll reply to you with a copy of the matrix as an attachment. I'll be developing similar matrices on other Peugeot models as time permits.
Merry Christmas!
