1979 Pontiac Firebird Coupe

Bought this without decals and some parts started. As I own the first issue of it, I could do some other stuff with it.
The fact, that the T-Top had to be cut out, I want to sand it down to have a coupe at the end.
Then in addition I'll going for a standard coupe like the 1977. No vinyl roof because the roof is smooth and plain.
Color not decided yet. It will not be red because there is one in the shelf already.
For the rims I'm looking for rally wheels instead of the turbo style rims.
