Thanks to Brad and HPH for the Koni deal. I picked them up on Friday and installed them yesterday. The rears were pretty simple.
For the fronts I checked Hayne's instructions first. They had a rather long list of things to do, like removing the brake discs. I was sure that it would be less involved than that so I unhooked the sway bar and then removed the taper pin holding the ball joint on. The pin came out fine but I could pop the arm off. I jack up the strut to put some spring pressure on it and started wacking it with a hammer at the end of a 2x4 (through the cutouts for the radiator vent). I'm not sure what it will take if I need to replace my balljoints but I decided to move to plan B.
I dropped the torsion bar and crossmember mounts. This allowed me to drop the struts enough to remove the struts. After that it was pretty simple. I have (according to Brad) mid-80's 911SC struts. However, I didn't need spacers on top of the struts. Brad searched a while to find some for me but it looks like I'll be returning them the next time I see him.
