Could be - I, myself, have quite a collection of unused left-hand side parts and an equally large collection of broken right-hand side parts 
Ummm, perhaps you should set up a Serpent parts trading section or open a for trade forum !
Over here, since we run clockwise most of the time, we break the left parts. The right side parts hardly break. So the LHS can sometimes be loaded with right side parts but no left parts available.
