Heck, if it's gonna be a whole winter project, do the whole shebang. I'm going to try and do my front end in a week or two, and I'm using PST polygraphite parts. That said, Zack Kanter (SoFasst I think) has a new high performance front end line out that you can find in the vendors section. Also, Bill Harper (a knowledgeable forum member to say the least) aka Navy Lifer, has assembled this list of Ac Delco
parts. Different strokes for different folks, some say poly squeaks, but I think most agree that polygraphite is much better than polyurethane. If you want to go all out, you can always use Bill's system, done here
by another forum member who's quite satisfied. Whatever you're willing to spend. Save the money on install, do it yourself, get top notch parts and a go fast mod with the money you save. Springs, folks say Global west for the front are the best, chopped 9c1's seem to be the economical way to go, shocks, bilsteins or hal's for lots of cash, monroe ss for the cheaper end. Anyways, lots more knowledgeable people than I have discussed this fully before, try a search on "front end rebuild"
