I also have this kit and it is a 1970 1/2 Camaro.
Looks good so far but I think the black lining looks a bit heavy. I glued on the front and rear valances before painting on my build to avoid any risk of damage with glue and to make sure the panel fit was correct. Doing it this way allowed me to make adjustments by sanding,filling if required etc. Might be worth considering next time.
