That is about right, it tapers up and back.
I knew I was using the 3" x .75" tow points. I marked the bumper for the material dimension at the frame intersection, remembering the thickness of the bumper material, I added .25", and tapered it up out to the expected end of the bumper,. I ended up cutting about .5" off the end, which is about .5" inside the body line. I think I am going to make some quarter protection...but will make a tire swing out and gas can holder first.
I dont remember why I chose the width of the main/middle section. I could not find any 4x5 or 3x5 so I just went with the 5x5, but I like having a larger place to put my foot and beat on if needed... I dont do enough wheeling to consider the extra 1-2" width a huge deal,,, but if I were to do it again I would try the 3x5 or 4x5 material.
I did not take any in progress pics, partially because I started this project 8-9 years ago before moving out of my warehouse in atlanta... the main body was easy, the lining up the holes for the tow hitch and tow points were a little difficult, but not the end of the world.
I did not want to remove the rivets that hold the body mount on so I spaced the 3/4 off the frame with some 3/8 material ground down so the 3/4 rests on the rivets and the 3/8.
If I were to make another I would do somethings differently, like not cut the frame. In my case I did not care, this cruiser will never have a stock bumper again. I would use the factory holes in the frame for mounting instead of drilling the frame-3/4. I know there is a better, faster just as strong, easily repeatable way of building a bumper without those extra steps... but this is what it is and works fine for me.
