Fixing the wires
Take one wire out and look for scratching marks (pic06 & pic 07).
Put some kind of plastic tubing with an inner diameter of approximately 4 mm over the steel wire (pic 09).
I used a balloon straw as often seen at fast food restaurants and children friendly shops (pic 08).
Reposition the wire in its hole and repeat the procedure for the other wire.
As the black coating underneath the coil springs was also worn heavily, I cut a piece of tubing carefully along its length and put it over the wire underneath the spring (pic10).
Now it's time to zip up and close the seats (pic11). Before closing you might want to test if the measures are sufficient. When so push the black strips at the three edges of the lining back into each other. Remount the folding table if applicable.
Make a test drive and enjoy the silence. Italian cars give that little extra joy to their drivers but do require a bit of tender, love and care in return.
