Datsun Roadster taillights are really close but they aren't cheap either......but you can get brand new ones. Datsunparts.com good luck,

these are the coolest I've found with 1000 hours surfing around looking for some rear replacements. Land Rover Series 2a rear lights are not bad but you need a seperate signal for turning...that doesn't really help. Tail lights are one a handful of rarest parts to look for. If you really want the originals keep checking ebay.
