Thanks! I think I will do some work this evening to see what the weight might be. I expect it will be heavy, but if it is twice the weight of the original spindle, might not be the greatest idea.
I did, the holes just below the UBJ mount are there just for that. But I didn’t think about ones around the hub itself. That’s a great idea.
That was kind of out of necessity. The hub covers the bolts and the bolts are too close to the hole to leave wrench clearance. And even worse, the hub has to be bolted to the spindle before the LBJ can be bolted on.
