I went thru the same thing you did on both my standard cab and my king cab. On the standard I bought one that was 4" and shortened it with a chop saw and welder. It worked great. On the king I couldn't find one so I combined two. No chop saw, used a sawzall... blew up and took out my gas tank and left me at the side of the road in rain. I paid 500$ for my one piece drive line. It's worth it.
