help with 348 rear

hey does anyone know any tips on fabrication techniques that i could use? i have a ferrari 348 that i am redoing the rear grille to be one solid peice and i will be using enzo tail lights instead of the stock ondes and they will be in drilled holds. i will post it as part of the ferrari 60th anniversary group build.

use a thin sheet of styrene. lay it flat, trace shape of 348 rear on to it. Cut it out, drill holes for Enzo taillights, glue to rear of 348 and insert Enzo tails. wahlah

thanks. next time i go to the shop i will buy styrene, putty, paint, clear, primer, and if i have money left a 612 scagletti.
