Really easy to add hitch. I eye-balled it seven times and tried to figure different ways, finally found a super easy way.
My BB International has "drop downs" where the tow hooks are bolted on, basically a short piece of channel welded to the end, under the frame.
I used a 4" grinder to cut out a square of steel from the sides of the channel. Cut the mounts off the end of a hitch that was from a Dodge pickup.
This left me with basically a square tube, 3" I think, with the hitch part in the middle.
I then slid it into the hole on one side, far enough to get the other side up and in. Then centered it up and welded around the end on each side.
It's not going anywhere. Towed my new bus home with it
Photo's are great, I'm just pathetically challenged at posting. I'll snap some and 'mail to you if you'd like.
