Are all the horseshoes on first gen the same?

Hey guys.  I just received a set of horse shoe trim and they all seem to be the same size.  Is this correct?  It always looked like one pair was larger than the other.  Likely an illusion.  I don't have any 63-64 Riviera's to reference and all my trim holes were shaved by the previous owner.

 

Thank you

Chris

They are the same in appearance but the way they attach is different for each year.

Chris. there are four different horseshoes. The last three numbers on the back are 402 and 403 for a 63 and 162 and 163 for a 64.  They all have 9 tabs. The main difference in the two years is the first two tabs spacing to the body. In 63 the first tab was not at the end of the horseshoe. When owners washed the car, rags would catch the horseshoe molding while washing or drying and break the tip of the horseshoe off. Then in 64 they put the first tab at the front of the molding. When installing these place the clips on the tabs then tap the molding into the body. Hope this helps. Gene.

Abandg thank you for the thoughtful response.  That amount of detail has helped me figure out that I have 64 horseshoes which is exactly what he needed.  The second question I have is: do they install in matching number sets?  Meaning do 162's install on one side and 163 on the other or is it a combination of 162 and 163 on each side?

Each side gets a set of 162 and 163. You can see this by the holes on your car. Gene.
