Headliner/bow question 1970 barracuda

Hi all,

I am having a headliner installed in my 1970 barracuda. The old one was removed at the body shop because welding was done on the roof. The bows were retained, but the old headliner was discarded.

There are some different lengths to the bows. Is there any rule as to where the longest bow goes?

Thanks in advance.

The longer ones go in the back.
