Hi Sergei -- On my '74 Argosy I installed new rockguards following
Janet's thread. Be careful in following those (or any) instructions. One should be sure to have enough room for the middle section before they arbitrarily place the side wing hinges -- like everything, plan ahead with a helper assisting with dry placement before holes are drilled. I didn't get to the point of painting my Argo and never even thought of segment protectors.
I can't help you create a poll with hierarchical branches dependent on a previous answer -- the software just doesn't allow it.
