Hello again Tony.
Re your question about the fitting of side protection strips.
All of my Panda's have the 1000S/4X4 type protection strips. I feel that they improve the appearance of the car and they save the paintwork from so much accidental damage. Where the car did not originally have the strips, I retro-fit them, using a set of templates that I made for the job.
Take a look at the on-line IPC under 1000S and 4X4. You will see that the strips ( they are actually five and a half inch wide plastic mouldings ) are key hole slotted onto a series of plastic studs along the side of the car. There are five studs on the door alone and the drilling of the five, eight milimeter holes, needs to be very carefully done.
If you want side protection strips, it would be a great deal less work to find some self-adhesive black rubber trims, usually of tri-angular section, which I understand can be obtained from car trim companies. Trims of this type were once available from Fiat, having the Fiat emblem on them but I have not seen any of these for many years.
