Old army trucks don't seem to have cup holders. When you go grab a burger for lunch there is literally nowhere to put the drink. And these old things are a double handful to drive. So, I made one that bolts to the steering column.

The fix : Redesigned the strap so that it can go over a hose clamp. Now you put a hose clamp on the steering column and it locks the rotation of the cup holder. I'll get a picture..
2/14/2018 - Yes it also fits the WWII WC series Dodge army trucks. I have on on my WC53 Carryall : https://www.eskimo.com/~jimlee/Home/Carryall_Blog/Carryall_Blog.html
I printed it 2 shells, 20% infill. Its set up for #8-32 screws & #8-32 nylocks. I forget the length of the screws, 1" ? 3/4"? But you do need one really long one to help seat the nuts into the hex holes.
11/12/2015 - #16 Hose clamp. (For 1 1/2" hose) For locking the holder's rotation to the steering column.
5/4/2016 - Screws are 1" and the long one to align the nuts is 2".
