Trimming out the interior today. Here's the driver's side top rail with the end roll and the little "holder" for it. The roll gets wrapped in vinyl with a flap the extends under the rail, then gets secured with three screws through that little 1/3-round aluminum tube bit.
Before moving to the other side I decided to template all the remaining pieces and lay them out on my material.
Not quite enough for the other top rail!
I've got a work-around but now hoping to find a 24 x 5-inch scrap piece. Anyone happen to have? I'd order another yard but the exclusive distributor of this material took six months to deliver the current order...
