Next I placed the tubes in a vice and started cutting them. Once you get almost all the way through the tube you should put something over the spindle thread area and bearing race area. I also placed a cardboard box with some crumpled up paper bags and pipe insulation under the spindle, so that when it falls it does not marr up the threads for the bearing retainer nut.
After you cut the tubes you will want to clean up the burrs left on the inside diameter and outside diameter.
You will end up with something like this when you are done cutting the tubes.
The next step will be to grind the casting nub off of the base of the strut tube. Just so that it is level with the rest of the base of the tube.
I did a small test fit of the S9 adapters and they will need to be pressed on, or hammered in with a block of wood or a dead blow mallet.

Then I ground down the knucle so that the S9 adapter sits level on the knuckle. You can see a small gap between the adapter and the knuckle. This is not good.
Here they are gound down, and level with the knuckle.
Next I tacked them up, and welded them all together. It is a PITA to weld in between the tube and the upright for the backing plate/caliper bracket stays. But I found an extended collett for the welder and did it up, breaking the collett in the process.
I still have to drill for the remote damper ajdusters, and at that time I will be gussetting the tube to the knuckle. I want to make sure that it stays in one piece. (It will hold up no problems, but I am thinking overkill).

Here is the upper plate that I made to adapt the z31 stock upper mounting points to the spherical bearing (pillow ball). Took me about 1/2 hour to make. I was very pressed for time tonight between actual work and "my work"
Here is one completed upper mount with the stance rear upper pillow ball mounted to the plates that I made.

Hey man! Sick Z! I read everything and i'm greatly appreciated of all the posted info about this swap! I have an 88' Z31 auto non-turbo with 257k miles and can't stay out from driving it. Love these cars and I can't get rid of it. So anyways, i'm saving for an RB20DET swap and from a 1-10, I want to know how hard it was for you? Can you tell me how much total you had to spend on the swap with tuning etc? My Z has the same exact paint job with the silver chrome trim. Is yours an 88' also? Tell me every small thing you can. Do tell! Thanks!
