I was searching older threads for something to replace our Boler's chrome wheel well trim. (first the driver's side trim fell off, then the date side...) and found this discussion, which was the closest fit.
I wanted chrome instead of white and found one source for 250 ft for $99 (yikes!), but then found this on Amazon: Cowles T5605 18" Chrome Edge Trim : Amazon.com : Automotive
for $11. The title
of the item says it's 18", but the description is 18'.
Unless I really mess up the installation, I'll have plenty left, so send me a PM and I'll be glad to ship the remainder for the cost of the postage.
