Replacing rear coils tonight, need some advice
I have already soaked all the bolts in WD-40, and am thinking I may need to heat them with the torch to get them off. Anyone have advice on aby other ways of doing it? I have thought of using the cutting torch and cutting the bolts, but I don't wanna damage the keepers.

Get ready to go out and buy replacement bolts. I snapped two bolts and a ratchet adapter when I replaced mine. My lower spring cups were fine, though. I am still using them. Lots of WD40, marine lube, etc.

I used a 1/2 inch breaker bar and pushed on it with my feet. Sheared the bolt off! Finally I broke my breaker bar! Heat...why not can't be any worse!

Need a bf hammer to drive whatever you have left of the bolt through the control arm once you break or remove the nut from the retaining bolt. An air hammer with a flat drift type chisel in it can work well for getting the bolt through as well. If you don't already know all possible cuss words by now you are about to learn. Then again you could be trying to get the u-bolts that hold the diff onto the control arms, the spring bolts are easy compared to those.

IT'S DONE!!!!!
Can't go wrong witht he torch. I ground off the bolt head on the first lower coil, and after that i said "F#@K THIS!!!! Took 10 minutes with the torch. The passanger side , upper was a bit tricky because the brake lines are right there. But I managed to stay away from them and cut the bolt. Now I have to buy all new hardware (nut and bolts) And install the new coils tomorrow night. I never realised how much the back end sags when there are no coils on it. It rests right on the diff.!!!! So I blocked it with a rough 6x6 until I can get the new coils in. Thanks for all the advice guys!!

If you're going to shorter coils, I highly recommend Early Classic Enterprises' shock relocation brackets. They relocate the upper and lower mounts to make the shocks more vertical. After lowering the rear, the shocks lay down so much, they hardly move, which means they can't do their job. When mounted vertically, the shocks have a longer stroke and can dampen better. This kit makes a BIG difference in how the rear reacts to bumps.
