The steering neck is identical, for both, as far as I can measure.
How close a spacer tube length do folks accept . I made a tube for my 70 roadster and am probably going to trim it down to about 1/2mm over my measurement.
I have a friends tube that makes it almost 2mm over what I was expecting. I will be doing the final assembly of his front end.
RGM shows 134.5mm on their offering? I was planning on 1mm less.
