Hey, wondering how this ended up! I'm having the same issue except that if I rotate the bolts slightly to the right then it will slide all the way in. However, then I cannot fastens the unit to the axle housing. Any other thoughts?
Hey hey, Im in the same boat as you and am wondering how the 199mm calipers fit? I have the stock 16" "split spoke" rims, did the fit work out in the end? Cheers
