Welcome to the club. I am in Titusville and I have two M109A3s. Since they did not come with beds and have a box instead, I am using the M105 Trailer for the bed on my projects. However, there is a lot that you can do with the bed. For one, use the bed for the new Bobbed bed. You can cut the bed down and use it. Do a search on Apopka and look how he did his quad cab. He used the original bed but just cut it down on his A3. If you are set on using the M105 Trailer, then you can advertise the bed for someone who is looking to buy. Please do not scrap the bed as it can be given away, traded, sold, or used. These parts are getting harder to get a hold of and scrapping them prior to trying to use them or sell them does not make sense. If you are ever in Titusville; give me a shout. Good luck!
