Here's a pic of the RPI ZL rockers test fit. You can see where the 3M strip just doesn't line up with the bottom of the rocker and won't stay stuck. So back they went and RPI says it will be a while. :(
I'm kinda thinking now that the GM rockers might look more seamless. I really don't like the way the RPI's will show the top edge of the 3M tape anyway!
