The grill wasn't custom on that kit, it just had the headlights with the on position, it was nice change but a grill with the headlight doors down would be great too. If revell adds the door scoops, taillight trim, and adds a stock hood they've got a winner. That kit is mainly based off the 68/69 kit already (ie. Engine components, chassis)
I doubt round 2 will be the one's to release a 70 charger, especially with how worn out that mold is. Revell would be the one , since they already related a 70 charger in diecast back in 2001 as "doms charger" . It was like a 69 rear mixed with a 70 front end.
