How do I measure correctly to cut out the floor to fit up front? Where the "V" is? And while everyones at it...How do I properly install this floor. What I want to do Is just make it flat all across. and make the floor height even with the 3 bench seats. Then I want to cut out a door each section, (back, middle and front) to open and close for storage. Can I just cut the wood out and set it in or do I need to glue it? Do I need to use foam under it. (I don't even know what foam is used for or while people use it. If someone could explane that to me)<br /><br /><br />Another question. In one of the bench seats I have a seat mounted in the center. Well it comeing loose. So What I figured I should do is put some wood under the seat and screw it to that. But there is foam under the seat. Is it ok to rip it out. I have no idea why it's there. Or do you sugest another way of doing this?
