Thanks mwa102464!
I edited my original post. He's not looking for the actual flavor, but a spot-on jolly rancher tasting juice!
like I said, take any flavored he likes, be it grape, cherry, lime, whatever it may be, add a small amount of the malic acid and sweetener and he can have it to his exact liking ! I know what you mean though PB, but if he finds a juice flavor he really likes, then he can turn it into Jolly Rancher by himself. I haven't seen any supplier advertising this but Geoff over at TV will do this for you if you ask him to sour it up and buy a bottle of his sweetener to make it as sweet a you like, talk to Geoff, in the comments section on the order page you just put sour me up, and BAM there it is PB
