Hello Bruce, thanks for reaching out. We do have one U-bolt with a 1-3/4" inner width, but it is a 9/16" bolt. They are 5" long overall and are threaded from 2-1/8" to the end. Take a look at the following:
- Replacement U-Bolt with Nuts for 1-3/4" Wide, Square Trailer Axles - 9/16" Diameter # 175130
I have provided a diagram with dimensions for you below. Do you think this will work?
