For a replacement hub and drum assembly you want to match the bearings. We have previously found that the Dexter # 84546UC3 matches the UFP HD1377. The difference between the # L68111 and # L68110 inner race doesn't matter as long as the bearings are the same.

This uses a # L68149 (1.378" inner diameter) inner bearing and # L44649 (1.063" inner diameter) outer bearing. I recommend using a digital caliper like the # PTW80157 to measure your existing bearings or spindle to verify that this matches what you have. I'm not sure what you measured exactly, but something like 233 mm (9.17323 inches) is way to large to be an inner or outer diameter of the bearings, races and seal on your hub.

I have attached a helpful diagram showing where to measure, along with an installation video for your reference.
