I currently drive a 1987 NA Rx7.
I recently put on some new suspension (Tokico Blue Struts with Tein Springs)

I realized I had some camber issues so I decided to pick up this set of Camber Plates off ebay. http://www.ebay.com/itm/PillowBall-Camber-Kit-Plates-86-91-Mazda-RX7-FC3S-Turbo-Non-Turbo-/380506924520?pt=Motors_Car_Truck_Parts_Accessories&fits=Model%3ARX-7&hash=item5897fae5e8&vxp=mtr
What I was just informed though is my real question.
The link to the camber plates above are only the upper mounts. Apparently there is a "spacer" I have to run between the upper mount and the top hat of the springs or else it won't fit correctly.

I believe I found the part (its called a upper seat?), but I am not to sure.

Does anyone have any information or links I can read about to learn more about it?
Or does anyone have a link on where I might be able to purchase one?

Thanks in advance!
