Berger, the swing arm measures 16 1/2 inches from inside centre of the cross tube to the end of the wheel lugs, I put a rule across the end of both swing arm lugs to get the distance in the centre, so we are on the same page.
Width between the lugs is 7 inches
The 67-6027 bearing sleeve looks the right way round with the long end to the right side where I have spacer 67-5890 fitted to flush of the end of the tube for the 67-6028 spacer to fit against.
I did note the 67-6027 spacer sits slightly under the middle/ inner bearing, you can see that on previous pictures. I thought should have been flush?
I have also seen the hubs with rivets or bolts in the centre, mine has neither, it is clean. May help identification
