Wheel and Wheel cover codes for Hemi

[lilwendal]

I'm looking fo a little help decoding the wheel covers for 68 charger. The broadcst sheet shows 23J for wheels which should be the 15 by 6 with the F70 redlines. What would code 07 be for the wheel covers?  I cant seem to find anything.  If this is the code for dog dish caps would the steel rims automatically been painted body color?  Thanks guys

yes all dog dish hubcaps up until 1970 were painted body color, after that 1971-up they were painted black-MATT
