I"ve restored a 1971 FairladyZ-L and am into it about .... mmmmmm .... with the paint and all, probably approaching $10,000 .... parts are VERY hard to find for RHD and especially that old. Best of luck!! I've been searching for the engine compartment ID plate for oh about 7 years without any luck. If I had known about this one ... my brother in Cambridge Ohio would have SWOOPED on the ID plate! If you decide otherwise on restoration I'd sure be interested in the ID plates.
Or a set off any 1971 RHD 240Z .... if anyone knows of one and wants to make a buck or three ....
