All of the hubs that we carry with a 4 on 4 bolt pattern that also use inner bearing # L44643 also use that same bearing for the outer bearing. On your spindle it would not be the correct size. If the inner bearing is actually 1.0681 then it is possible that bearing # L44649 would fit which has an inner diameter of 1.063 inches.

If so the hubs that take these bearings all have a 5 on 4-1/2 bolt pattern which would mean you would also have to replace the wheels to match and possibly the tires depending on the exact size you have now.

I have included a link to the 12 inch wheels we carry with a 5 on 4-1/2 bolt pattern as well as a link to the hubs that take inner bearing L44643 and outer bearing L44649.
