I've never done a rear but here's the parts and a pic for the front:
#6271375- Bracket for sway bar brackets to frame. Cost $9.49 at Dealer. Need 2
#334671- U shaped brackets for sway bar bushings for a 1 1/16" bar $4.29. Need 4
To fasten everything I used 3/8 x 1.5" Grade 8 bolts, nuts, flat and lock washers. You need 12 of all these.
I used poly bushings from the auto parts store but you can get kits with bushings and brackets (not frame brackets) for the sway bar. Here's a pic of one installed.
Sway Bar It shows the brackets and the way the sway bar needs to be installed (yes it can be installed upside down but not as effective). You can see the frame brackets I'm talking about in the pic. If you already have these then you won't need them. I decided to go to dealer rather than junk yard since factory ones are riveted on and hard to get off.
BTW: Chuck I've got the one off a 77 or 78 van Mike's talking about. It has 4 brackets on it 2 from the original and more from the sway bar I got from another guy here. Let me know if you need it.
