Trying to replace the soft frame-to-axle brake line on the front of my '75. The frame end is M10 x 1 female inverted flare, but the other end is M10 x 1 male, squared off (not inverted flare). I checked the tee this treads into, flat bottom. Not sure if this is original, or PO work - just...
Same thing happened to me. I pulled the knob / remaining cable from the housing. Cut the cable off and had my neighbor TIG weld a piece of filler rod to the end of the knob assembly. Works great!
