Hey, I just purchased a parts truck that had a chevy 350 in it and I parted the truck out and am selling the adpated to my friend. Hey has his own 4.7 to 1 t-case and was wondering if we need to swap the shaft and adpater to his case or just my adapter? I have the other whole t-case minus adapter just sittin in my garage. WIll he need that shaft?
