I am having difficulty sourcing what I would call the upper spring retaining plate or cup, on the front strut i.e. the removable plate below the circular plate with spigots that attaches the strut to the bodywork. I have a part number 5031.38 - would this be correct, and if so where might I get a pair at a reasonable price? Many thanks for any help on this. (I am in N.Ireland and my car is a diesel estate '95. I believe 4E is the designation, though I also think that the age is immaterial to this part definition).
