I just recieved a COA for 1 1970 911 T which lists a leather sports steering wheel, 363mm. Was there ever such a thing. I thought the wheels were 400mm for standard and 380 mm for 73 RS's. I think it is a standard wheel with a leather wrap which was standard on S but optional on other 911's, any ideas. Also where do you measure diameter of steering wheels is it an ID or OD.
Thanks,
Phil
