Little update, I did all the body mods, just need to fix the hood's curve and then it will be ready, I just painted it recently, and next to the car you see some rims I made for it. They re based on the AMT Chevy 57 kit, and seem to be looking fine. Around those rims I put some widening from the original box, so it looks fine in size.
Thanks all for looking and for the nice replies.
