Yes, its the 58 on cast iron hub one, which fits the forks with the clamps.
I picked up a TLS front brake plate on which I had the lug slot ally welded deeper and machined back so it meets with the fork lug properly. I have now found a later wheel with the flange which is what goes with the TLS brake. I thought that if I could find a spindle, it would save taking the one out of the wheel I already have on the bike.
One question on yours, you machined a new groove - did you machine both sides and move the wheel over, or did you machine one side only and "Spring" the legs closer together ?
