This is not quite the right one but you can get a similar one for the Pierburg carb. It will stick through the bonnet a bit but whatever you try it will do the same and it looks pretty cool proud of the bonnet and gets plenty of cold air. The 2 retaining nuts are dome headed and IVA friendly to.
Well Done.....AndyH
