well just to put things into perspective i went to get some electric roof pins made today for my mk4 cabriolet and one company wanted £40per hour now these pins are
40mm long 13mm wide but would take around 1hr to make so i would of been looking at £160ish a set these aren't rs parts but ford don't make them and they are very very rare to find any genuine ones around one lad i know sold a set of 2 of the bottom ones for £40 but i have found one company who can do me a set of 4 for £30 posted so even when you try and replicate something it can end up more than ford would sell them for even if they still sold them so its not jsut rs parts its ford parts in general as our cars are getting older and parts are being dicontinued etc
