I thought this was a bodge patch but have seen similar on other Defenders. If it is meant to there, what is it and how do I get one that ain't fooked and oxidised through?
It is one part of the cappings, there are different parts to make up th whole capping, they just pop rivet on to the body.
Series had em galvanised, think you can get them too if you want, or just remove, sand, and paint again if you want to save money,
Just riveted on, so should come out easily enough.
As said, have a look through the parts book for the part number and you can order from that.
I use this online version. http://www.allbrit.de/NAV.cfm?SPRACHE=EN&PAGE=338364
