Here are pics of the spacers. I must apologize, I only have two 20mm spacers, not 4. It has been long enough since I traded the Z that I thought I had taken the rear spacers off before I traded it. Well, I didn’t so two of them went with the car and I have the other two. So for those of you who only want two you are in luck.
Keep in mind you will need new lug nuts for these as the ones I have are in bad shape. Two are missing (they were damaged beyond use) and the others are slightly rounded on the edges. The pictures show their condition. The spacers themselves are in perfect condition.
