Sorry for the delay. I didn't get decent pics either when I was replacing the lip.
I got a couple of pics. The first shows what I did to the wheel, the second shows the channel that the lip goes onto.


The actual process was easy. I pulled the damaged lip off and the only part that took any time was removing the previous glue.
The new lip sits in a channel and it is impossible to put it on wrong.
I had thought that I could have taken the lips off all of the wheels some day and painted them but they are scrap after they are removed as they go out of shape.
