I have a 12/69 K0 and have a couple of the 3 way brake line joints as the parts book calls it. The John Wyatt book shows an early K0 to have a red plastic end where the brake light connection is. I have another joint which does not have the slot for the brake line and the plastic is black. Could someone please let me know which is the correct joint to use. The bike I'm working on was a mess and far from original so I'm questioning most of what was on it.
Thanks for any help you can give.
Cliff.
