I recently purchased a 9 month old red body blue bar female from Amazing blue reptiles...I do remember her saying she had some brothers available. If not...try Pams chams, she has some nice red body blue bar's...Im not shure if there breeding age though.
Pam is selling off her breeding stock last I heard. She may be a good bet. You will probably need to call her, as I think her email gets VERY backed up check out her website www.pamschams.com
The Nozakis, aka Amazing Blue Reptiles, do have a few very high quality red bodied Ambilobes available. They are taking a trip to Japan for a couple weeks though, so they might not get back to your email until they return.
I got this guy from LanceCham here on the board. He posts on Kingsnake as well. Tell him Matt sent you if you end up talking to him. They're about 8 months old, and big for their age.
