Wiper arms & blades!??

Could you please tell me the correct side to fit:
Arms, one long & one short
Blades, one long & one short
(The garage book shows the pass side blade as the longest)
It gives four possible combinations!
Many thanks,
Simon

im sure the big one go`s on the drivers side
fit it and find out, if its rubbing on the seals then its the other way round
gary

shorter blade is drivers side cant remember which way the arms go

Both the above kinda agree, long arm / short blade for drivers side.
(I know the longer blade is listed as the passenger side)

Just looked at the ones off my spare shell.
The longer arm is the passenger one.
The longer blade goes on the drivers one.
Unless it is post 92 the drivers arm should be easily identifiable because of the threads for the aerofoil.
