There are guys that stamp the fenders they charge $350-400 a pair PLUS SHIPPING if you're not close. After you do that combined with buying the new head light buckets that Alan mentioned. You are almost better off buying a pair of new 71 Fenders. With the available discounts you can get them for like $1000 a pair. As Alan said you will also need the header panel and the mount plates in the ebay link above. Front valance, insert, valance lights, grille.....The 70 to 71 conversion is about the most expensive thing you can do.
