A year ago I cleaned the case of the C^ with some brake cleaner and a detailing brush. I remember there was some paint overspray on the bell housing and tailshaft. Figured it was someone careless in the past. Now after some educating I guess i cleaned off the markings which had been applied at the trans plant. I cant remember what color it was. I've read that 69 CJ's with a C6 had black markings. What would a 68 S code C6 have? Pics would be great if you have some.
