Hi all, I got my build sheet (punch card copy) from Chrysler Historical some weeks ago. Price was around $ 50.00, expensive for 3 copies of the build sheet and a hand written explanation ! no infos about options codes, schedule date etc.. Fortunately i know (at last for '57) the codes of the data plate ! i've put on a page of my site (http://www.ifrance.com/c-i-f/chs_us.htm) one pic of the card and the explanations about code deciphement. You must also go to the data plate page to know the option codes (ther's a link on the page). -- Philippe COURANT (Pau, France) Imperial 57 Crown convertible Buick 58 Roadmaster sedan - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
