Hey all!

Not sure what they are called - but looking to make the upside down U shapped thing above the back seat passengers heads chrome.

I found them a long time ago - come in two pieces for each...
what are they called?
where is the best place to get them?

any help I would really appreciate!

These? IDK but we have them. I don't know where to get em.
I believe they're called Chrome Roll Bars.
