please help with timing marker

ive been on a serious search for a timing marker and cant find one. they have been discontinued for years now and there are no more in stock. ive had nissan run parts locater searches in the u.s. , canada, and mexico. ive also scoured the local junk yards and called numerous z parts shops. its for a 1971 240z, but the single point marker was unchanged until late 1973. the single point or the one with the degrees marked on it is fine. if anyone has any ideas id be very grateful . thanks all.

-----also does anyone know if the position degree of the single point marker would be accurately represented with the multiple degree marker (i.e. interchangable), since there off (i think) early 260's and 280's. :classic:
