Funny you should mention J.R.Hartley - I know his son!
Well, sort of. After the success of the advert, my friends father wrote a book called Fly Fishing, under the name of J.R.Hartley. And made a tidy sum in so doing.
As an outside chance try Modena Performance in Germany. They have done several V8 conversions on Ghiblis and when they do this they remove the fog lights to fit the intercoolers. http://www.maserati-tec.com/html/index.html
Arthur I like it, they may have some knocking around, failing that the modified grill is a nice modification. I will dig out my best pigeon German and give them a call in the morning. Thank you.
