For spoilers and fibreglass panels try this site:
www.showcars-bodyparts.com/datsun.html. If you Stateside guys are really keen here downunder in New Zealand we have a range of
fibreglass and carbon fibre panels available. Front and rear spoilers, front guards, coupe doors, bonnets, boot lids and dashboards. I've also seen coupes here(racecars) with
fibreglass tail light panels and rear quarters.
