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
They should be the same size top and bottom.
DO NOT modify the bushings they will not take them back if you do.
For what you paid for those shocks make them supply the correct ones along with a pre paid shipping label to return the ones you now have.
