I have no idea what part you are talking about.

the crush sleeve perhaps? For setting pinion bearings preload?

I wonder if he is referring to the copper washers on the studs that retain the third member.

This is what he's talking about. I'm using one from Strange Engineering (N-1910) that's very similar.

It takes the place of the 9" crush sleeve using multiple thickness shims between two billet end pieces. Add/remove shims to achieve the correct rotational torque. I torqued my pinion nut to 175# and began checking rotational torque. When I had the correct numbers, I lock-tighted the nut. I'm not sure what my final pinion nut torque is but it is substantial!

It's called a solid adjustable pinion spacer I think.

Your very welcome. I was a little confuse when I got mine, called Strange and got all the info i needed to set it up correctly. Typical of any rear setup, lots of disassembly and checking.
