Question abt my new Bilstein dampers. (shocks)

I recently bought a set of 4 Bilstein's for my 67 Barracuda.
The front ones are installed, but when I went to put the rears on, they wouldn't fit.
The bushing in the upper eye is too small in diameter by abt ".075
The bushing is not rubber, I tried with some vasalene to force it on but that was no go!

The vendor says it is the correct P/N for my car. Maybe wrong bushing installed in my parts.

Here are some pics.

I would like to know if anybody else has had this problem and what did you do to resolve it?

I think you can plainly see they are not the same size. They NEED to be the same size.


I'm thinking drill them out if I have to.
Rather get correct part.

Thanks, cudamike13
