My 68 Cuda Trunk Trim from Steve Clair Young

Nope!

I used them to ship parts in tubes.

Unless something changed in the last year or so...

EDIT:

Hi Mopar Head, just checked on-line and you can still ship in round tubes. You may be charged a little more because the sorting machinery has a hard time moving a round tube so its sorted by hand.

Better than losing a rare 50 year old piece of trim though.
Just put the round tube in a cheap rectangular box, problem solved! That said, I had him do my grilles years ago and it was a big improvement, but not stellar for sure. The clear is peeling and it was black stripe tape which started peeling right away, instead of paint. ALWAYS stored inside out of the sun!
