We acquired a scrap 306 1.4i single point injection 1995 model for my son to learn to drive in. The MOT failures run to two pages.
On the way we found that a balljoint had been replaced in the past, but the metal shield was missing.
Here is a quick and simple shield I made from an old CD-Rom casing.
I copied the existing shield. It took about 40 minutes to make and cost nothing (which is what I like).
