I needed more interior storage and the overhead space seems like there's lots of space. So, I ended up making some mounting brackets out of some aluminum stock I had laying around to mount to the oh sheet handles. I used 4 aluminum sheets, about 3"x12". Removed the handles to line up the aluminum and marked the handle holes. When drilling out the holes, I marked up and drilled out 4 holes on the opposite end to mount the rack. I'm using M8x1.25 25mm bolts with nylock nuts. So, drill out big enough holes to fit. The rack I'm using are Saferack 18"x36" wall shelves with 500lbs weight capacity. Here's the end result... what do you think?
