Two questions - wood bed, and roof marker lights

[Mountain Man]

Two questions for the experts, as I look for a new project new questions come to mind.


1. I don't like the cab marker lights on the roof. How much work would it be to get rid of them. Is there a major hole under the light assy? What have some of you done, or recommend.

2. I am finding trucks with new paint and new painted metal bed strips, but old original wood still inside. How hard is it to replace the wood with a new wood kit? Can I change out the wood strips without removing the box from the frame?
