My car is an 11C build Nov. 1968. If I am reading Jerry's book correctly then my rear spoiler is the smaller version that is not even with the quarters, so the tension rods in the trunk are the same size. However, I do have the hole in the subframe. If I am reading your responses correctly then ONLY D80 had that hole correct? Other cars that did not have the spoiler option at the factory does not have the support rod bolt hole. The other thing I noticed specific to my car is there is no emblem on the trunk lid? Is that correct also?
