Spare tire pic ?

yes, The ring holds the board down.

So to do it this way you need the "long" bolt.

I believe there are 2 different size bolts.

The pic you showed of the green car looks like a 67-69.

Wonder if they changed in 70,because my car came with the "short" bolt.

Adam,
So the way you have your spare:
Does the jack base hold the hook to the rim ?

Still cant believe that the factory service manual doesnt even show how to secure the tire.
