Nice work so far. I noticed the same issue with the wheel not fitting properly until i gave it enough force. i do recommend when you get to the taillight, cover the inside with chrome foil to reflect more light back through. If you're really 'into' Knight Rider, you can install a led scanner into it.
Just for you Mm, the KR kit makes a good S&B3. one needs to fill in the front scanner. The real trick it to find the stock emblems.
cameras aren't cheap, so i'd suggest open the curtain and get some light on your subject. also take from further back if your camera doesn't have a macro setting (flower icon).
It looks like you're doing a heap of work on your charger. cutting out the doors will weaken the body, so you'll need to reinforce the sills to compensate. I find cutting the doors is easy compared to building the entire door jamb (you have to do both door and body edges of the opening). what are you doing on the chassis? it looks like you're tubbing and removed the transmission tunnel?
