i really admire you guys that go to the time and trouble and research to build an accurate scale model. i just butcher most cars[neatly] mostly old F1,s, if a wing or nose doesn,t look right to me i just buid new ones to what i fancy. i,ve even changed an airfix kit of an mg magnet or suchlike[i,ve forgotten what model it was] but the rear[rumble] seat was plasticarded over and a spare wheel put on top, its got a bently blower on the side and 4 ally exhausts each side, teminating in fishtail silencers , dropped into the weeds on a 1,5 brass chassis with a loose pod holding a cheata motor. i t really shifts and holds the track good and its not as bad as it sounds. just like a garden shed build. even new cars dont escape. i, ve just put narrow group 5 type wing on a porsche fly gti evo. it completely changes the appearance and i,m happy with it. john
