I am NOT 100% sure about this. However, if you would like for me to mod your FB+, I would be willing to take it. If I cannot mod it, I will find a really nice FB 2 and mod it for you. Normally it's around $50 to mod someone's Flashback for them. However, I would be happy to do it for the cost of the mod kit $35. That removes your risk.
Of course, you can order a mod kit for $35 from me if you want to do the work yourself.
