RC2 has been horrible about putting anything on the outside of the box to let you know what is actually inside the box. Do you know what versions have the OHC six inside? Does the JL version with the yellow & black car on the box have it? (box doesn't mention anything) Does the blue & green "muscle cars" box with the blue car have it? (again, the box doesn't say a word about it.) I'm pretty sure the '69 Trans Am labeled version doesn't have it. Thanks for any help.
