I got mine msd coils from auto barn because by the time you pay for postage from ebay they are pretty much the same price & if you get a set buy some leads aswell custom made ones are a lot better than any brands leads, a bloke in kallangar QLD makes them
When you paint your engine cover use the heat of the engine bay to your advantage to bake the paint ,and do all of the sanding as suggested
I lightly sanded mine ,used plastic primer and gave it a couple of coats sand between them
