Will you let me or the forum know if you can mix and match the wheel halves on those when you get them? You could on the Fake 4" tri stars to loose the offset of the hub. so you could make matching wheel sets if you bought 4 or used say the long hub in the rear and short hub in the front etc..
On those I would take a blank sprocket and push a flanged bearing through it which would fit in the hub on the inside of the wheel halve, that would center and match it to the wheel and put the bolt holes flush with the sprocket would to use as the guide to drill the holes in right spot. Wish they would make another batch of those wheels!
