Question about 70 Z/28

[mister_copo]

I have a good friend who bought an original low mile 70 Z28 a while back, and now he's detailing it and readying it for Nationals. The jack, base and cover are mint, and when he removed the tire iron, we were looking at the sleeve that holds it to the jack, and wonder if it's the correct one or not. I ask because we have a few different sleeves all slated to be originals and they are all different. One is from his 70 Pontiac Ram Air (left in picture)- long rubber one, a short rubber one sent to us by Jim S (middle of picture)that was reported to be for a 70 Z/28, and the one that came on this low mile 70 Z that is a short foam sleeve (pictured on the right). Can you look at the picture in the link below and tell me which one is correct? Trying to make this car perfect. Thanks for your help guys.
