[FRENCHBLUE72]

O.K i bought a used bedside today for my longbed 72 and a used passenger door 50$$ couldent pass it up and they are nicer than mine ........So on the door there is some trim a thin piece just above the door lock that runs the length of the door and a fat wide one that runs on the bottom bodyline of the door ....How can i get them off with out killing them ,I only saw one screw ??Do i need a tool or what..... Who made carrage bolts those are a pain in the a$$ to get off so im gonna use regular bolts ,they should work right or do i need carrage bolts? And one last ?? what should i coat the inside of the bed side with ?????

thanks luke
