    You'll have to use the flat 6.0 flex plate with a spacer and probably elongate the torque converter holes. Thats the only way that trans will work behind the ls engine. It's cheap and easy. Factory a/c is easy to keep as well, not sure what compressor your truck has but there are kits out there to keep it. I used dirty dingo DD2550C mounts. Worked perfect.

    I have heard Dirty Dingo mounts work well. I just made a deal to get rid of my daily driver 2012 Jeep Patriot (what a P.O.S.) so the $ I have left over from paying my loan off should more than take care of this swap. I planned on having the tranny rebuilt since it was out. Should I just switch it over to a different one that is more applicable to this application? I have not had a wire harness built yet either. Planned on going with a Nelson one. Any suggestions?

    If you have the money ($950+) I say go for the Nelson harness. But if you want to try and save money, you can find a junkyard harness and have it modified or take the time and research how to modify it yourself. Either way you're going to have a standalone harness with minimal connections to plug into the body. As far as the trans, I would personally find a 4L65E or 4L80E, cuz even a rebuilt 60 probably wouldn't last you too long especially after modifications.
