And also from my experience there are lots and I mean lots of differing parts that were used on the Boreham cars that were designed, tested and tried on the cars, some were adopted as parts to go forward for homogation some weren't...a lot of these parts were still circulating in the uk in the late 90's/early 2000's...mis matches in parts like that often caused issues whilst trying to build a car...the funniest story I have is the WRC steering gaitors used on the easy feel racks...and trying to identify those!!!
