I saw his great installation for the fuel door in the bed, although I couldn’t find an 80s door, I found a long one off or an older Jeep Cherokee. I’m also surprised how many in the upick lot are plastic...so...started with the rectangle and started cutting...at the end I had the bottom of the bed sprayed at ProTec here in Raleigh...I’m very happy with the results
