Dunno why I went all black - just prefer the look to be honest.

If it falls off after a while I'll redo it or maybe remove it an polish it. As they are all fitted with e-clips I can take them apart very easily.

Springs were crazy money for just 4. If I wanted to by a few hundred they would have been much, much cheaper per unit.

Pins I have made by a friend but as you say, making batches of them would be pretty cost effective. The only problem is that each catch seems to be a slightly different size. I don't think fiat were too bothered about tolerances when they have them made! I had to do a bit of filing of parts to try and get them all the the correct sizes to work with the pins.
