I can verify Tim's theory,
The guy we purchased these from said he bought the set for his FE/FC (I cant remember which he said.) in 1958 but never fitted them.
The paper slip with part number was in bag with plates but bag was open, could have been another slip for the front set..i presumed part number was for whole set.

Interesting that Holden / Nasco would sell set in halves ?? Cant imagine to many rear sets being sold solo. But thanks for the info Tim, I love this kind of trivia.
Dee, No other markings on my plates other than LF, LR, RF, RR..
May get a chance to fit before Sunday and i take car out to Bigriggen
