I hadn't heard of any others either. The guy I bought mine from obviously barely drove the truck with only 898 miles on it in 9 years, but when he went to open the tonneau when I went to pickup the truck, I was ready to laugh when first he pushed on the lock cylinder thinking it was a button to open the cover, and then he went to stick the ignition key in the tonneau, and my jaw nearly dropped when the key actually opened it
I'd love to have #356's tonneau rekeyed for the cylinder to match the ignition too
Do you remember how much it ran? And were they able to do it with the cylinder still in the tonneau, or did they have to pop it out?
