The lines pass thru a bulk head fitting and they seal then selves.
Quick up date as of today. I have about 6 pin holes to fix in the cab before it goes out for sealing, one small dent in the new set and need to start body work on the tail gate. The rest of the truck had its last block sanding today down to 600grit and is ready to go out and get white epoxy sealer sprayed on. Then it comes back and gets a quick 600grit scuff then color and clear

This thing turned out so damb straite that it will look unbelivable once it gets sprayed. I can't wait to finally get color on it, it's been a long road since he first bought this truck.
