I was dissasembling and cleaning some CV's/axles to powder coat and rebuild and thought of you guys when I saw these paint markings.
I also dug up another set to see if this was a fluke, see for yourselves. The first two are from a 73 1.7, no gaurantee BOTH are original to that car, thus the possible reason for the diffe rent colors. The one on the right is very faint but is DEFFINITLY a white paint mark.
