Spare tire vibration spacer

[macrisel]

Okay, I'm on the home stretch getting my tub ready to paint and I almost forgot to drill the holes for my spare tire spacer.  I found the measurements for it off the the 2A site, but when I laid it out it seemed a little close to the carrier.

Two questions:
1.  Is the spacer supposed to hit the wheel or the tire?
2.  Does the spacer actually make contact with the wheel/tire all the time or should there be a small gap between the spacer and the wheel/tire?

I am using 7x15 tires.
Thanks!

I found out the hard way why these are needed. My spare tire carrier cracked on the '53 and now I need to fix it and add the vibration dampener. My '49 still has the original one.

Thanks Larry, those are the drawings and photos I had.  I had roughed out a spacer, and laid it out on the tub accourding to the drawings, but it wasn't hitting the tire and wasn't thick enough.  Looks like I need to move it up the fenderwell a little bit and make the spacer about 1/8" thicker.  I'm using a reproduction spare tire carrier on a reproduction tub so it may stick out a little more than the factory one and be in a slightly different location.

I'm assuming it should hit in the "fat" part of the tire?
