I need to raise the ride height of my 81 back up. I have a very large stereo system wieghing about 200lbs in the cargo area. How do I do this?

tighten the bolts on both sides of the rear spring and then.... your done!

just make sure you tighten them even amounts (count your turns)

It may not be easy to turn those bolts because of rust/scale/dirt on the threads. Clean the threads off with a wire brush, spray it with WD40, and use the technique - tighten a half-turn, loosen 1/4 turn ... tighten a half-turn, loosen a 1/4 turn. When using the wire brush, ... use a lot of elbow grease and it will make the wrenching a lot easier.

I only have one rear spring????I am confused, Anybody have pics of what bolt I need to tighten? Is it like torshion bar on a chrysler?

That spring has a long bolt at either end which anchors the end of each trailing arm to it. By tightening those bolts you are pulling the back of the car UP. If you run out of threads you can get shorter bolts; just make sure they're Grade 8 minimum.

At this point, before turning any wrenches, you should get a service manual and flip through it to at least gain a passing familiarity with how your car is put together...

Read and understand before you even touch a wrench. I have been baffled by many a project before I got on here and asked the right questions. Search through the archives here for pictures of some nicely put together rear setups and that will help a lot in understanding what people are talking about. Look at the long bolt a few inches off the ground just inside each rear tire and it will start to make sense.
