I want to install a diamond plate shelf approximately 12" from top of storage bay for storage of lawn chairs and light bulky items.<br/> <br/>When I drill it will I hit a hollow place for toggle bolts? Is it solid for lag bolts? <br/><br/>How much space is between top of storage bay and bottom of finished floor?<br/><br/>Any advise appreciated. <br/><br/>Larry Bradley<br/>98 270<br/>Jeep toad <br/><br/>
