The dukes charger mold was rumored to be retired after 2015 because of the Warner brothers pulling dukes licensing. So we may not see this mold return, plus someone at round2 told me the mold is very worn out.
I have both original 66&67 annual charger kits both unbuilt and 100% complete and the 66 did not have the clear hood but the slot car option. The 67 had the hood but no slot options. The street machine version that has just been rerealesed is based on the 1974 reissue that had no clear hood, or slot option. The street machine release has a mix of the 66&67 annual releases and the thunder charger from 1967.
I just bought this kit yesterday, I can confirm the it has every piece from the 1974 release. It also has a mix of the 80's street machine release, and a few thunder charger bit. Very nice job from round 2 on releasing a nostalgic kit.
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.
