Well there are several options available for the springs.
Vogtland are the most popular and the sedan springs will fit on a wagon, there are several different spring rates available too. Look for a company called Rustic Racing, he is a B-body suspension guru and can answer all of your questions. He can be a little hard to get a hold of but he does know his stuff when it comes to the 91-96 B-bodies.

Well I would have figured he'd gotten most of that sorted out by now.
At least email him and try and get some part numbers out of him.

I have H&R springs on my wagon personally but I have no idea how low they are or how they ride. My engine decided to spin a bearing the night of the swap right as I was taking it out on the maiden voyage.

Yeah he ignored me when I tried to give him money so I canceled my order with him, I just figured that in close to 6 months he would have fixed this problem.

Back to the original topic, all the springs listed for a sedan will fit on a wagon, if you plan on still using the car to haul stuff you will need to use air shocks or air bags that go inside the springs the keep the rear end from bottoming out.
