[Chevelle-List] Caliper Question

[Misterbowtie66]

Hello

When installing single piston calipers, the calipers are marked L & R . My question is as follows.......

Caliper marked  R  ( drivers side or passenger side ?? )
Caliper Marked  L   ( passenger side or driver side ??  )

Thanks again........John
