The new lower control arms come with the inner/outer bushings already inserted - ask whoever you're buying the parts from to confirm. If they say that's not the case press them to make sure...they've been included on the 4 sets that I've bought in the past 5 years.
You should probably get 6 of those special bolts (the ones with the hole in them that allows you to wire the bolts together) at the bottom of the strut (where it connects to the ball joints). The heads on those bolts get pretty rounded because they can be a pain to get to - plus they're probably pretty old by now. These bolts are pretty pricey.
If you take apart the struts you could also get new spring pads.
Sway bar bushings - 8 total, SB bushing bolts - 2 total, SB bushing washers 8 total. The bolts get pretty banged up so it's a good idea to order them.
There are also two special plastic washers that go between the tie rods and the centerlink.
The idler arm bushings are a two part bushing (upper and lower). However, I'm not sure if they're sold as a pair or individually. My old rcpt shows them being sold as a pair but the Bav Auto website says "two req'd per car." You may want to check on that. (@$20 each - wow!).
You'll need new cotter pins for the lower control arm bushing nuts and the idler arm bushing nut. The rest of the stuff should come with new lock nuts or nuts/cotter pins (e.g., ball joints, tie rods, center link etc). You may want to take a quick look at the rest of the fasteners to see if anything looks rounded or suspect.
While you're doing all of this you could also do new front wheel bearings, brakes, brake lines....
This is one of those projects that can make a heck of a difference in your enjoyment of the car. It's not too hard but it will take some time, tools, &muscles and you're going to get pissed off a couple of times (esp with the compliance bearings) but it's well worth it!
Good Luck!
