Firstly you don't say what 1966 MK2 model of car that you're after. I'm going to guess at the Ford GT40 (or maybe even a Jag). That info would help.
Secondly, and probably most importantly, are you sure you've posted your thread in the correct area of the forum? This is the Project Cars 3 section, so you won't get much response with your request. For 3D models I'm going to suggest the Assetto Corsa section is your best bet - which is over HERE. There's a PC mods thread which is mildly popular.
