Just a heads up, 12 isn't enough torque on these plugs. They back out and then they eventually blow out and strip the threads on their way out. I believe I saw the new torque that ford updated to was 32 ft/lbs but I'm not 100% sure. You should be able to find it on the forum pretty easy.

The modular heads can withstand 100 foot lbs of torque, - over and over again without damaging the plug chambers. No plug can take that much torque, - the heads can. The problem was and still is too little torque.
OP doesn't have a modular engine, so, yea, none of this applies lol.

Question how hard is it to change the rear end on a 2wd. I found a complete rear end barkes and all for under 140. It has the limited slip. Mine don't right now. It's the 3.55 I've got the tools and time but just wondering how hard of a job it would be. Any tips?? Also is it worth it?
