Yeah, those shouldered bolts are hard to come by. They used them on the J.C. Higgins beehive springers as well (for the rocker plates).The rat trap was missing a bolt, so I was on the hunt to find one. It’s very specific, so I didn’t think I’d find one. So I talked to my fab shop about modifying an existing bolt. They told me it would be easier to run some 5/16” hex stock through the machine and make one.

To this… which one is the original??

Without it I guess. If it’s vital to the operation then I’ll figure something out. But the way it sat at the fork, it didn’t look usable without some weird addition. I think it came off a Columbia, and that chopper fork is a lot different.Now that the mounting tab is cut off, what is your plan for mounting the hub?
Love that fork and such a clever solutionIt is a vital part of the brake. Think of it the same way you would think of a brake arm on a coaster brake hub. It has to be connected to the fork to work.
However, in this case, you will not be able to connect directly to the fork. Instead, the hub will have to connect in some way to the rocker because that is where the axel is mounted. If the hub is connected to the fork, it would negate the springer action.
I had the same issue with a Worksman drum brake on a rat trap fork several years ago. I was able to make a bracket that would bridge the rocker and drum mount together. Since you are changing things and planning to chrome the parts anyway, I think you will have a lot more freedom to create a 'stock-looking' mount that will blend better than just adding bolt-together brackets like I did.
This was my solution:
This is the rat trap fork. It's basically the same as yours except that it has extra trusses.
I feel like with a strut in place back there, it'll tug down and glide a bit better over the tire and wheel., it looks nice from here, otherwise?
Yeah, maybe you don't want to interrupt the lines, but there are holes on the fender, and holes on the dropouts, so, a strut would pull it down nice. Not crazy outta whack without, Most wouldn't notice, but to all of our "trained" eyes who see the little difference, sure, not a perfect fit. If you don't want a full strut, maybe a short one to to the top of the seat stay?I feel like with a strut in place back there, it'll tug down and glide a bit better over the tire and wheel., it looks nice from here, otherwise?
