Hello everyone, hope all is well. What I have going on at the moment is a proposition for those doing an injector swap in the near future. I am wanting to go to AD injectors, the truck has some super tired AB's in it currently. I would like to trade someone my AB's for their AD's to send in as cores....obviously I do not want 300,000 mile used AD's, but if you have a good set and are just wanting to go bigger please let me know if you would like to swap and can send mine in as your cores. Thank you......JOSH BYERLY
