Sprint Pannier Guide Bar

HI All. I went for a short ride the other day (without the panniers) , and when I got home I noticed that the pannier guide bar was half hanging out of the support tube !! the ball knob on the end of the shaft had come off !!! Does anyone have a spare one I could buy, or does anyone know where I could purchase one ??? Ive looked on ebay and other sites but nothing available. It measures 37mm dia.

 

phot attached ...

 

This is an earlier photo showing the guide / slide bar in position. I have now lost the right hand ball knob

 

Yes , I've seen the link before - as you say … ouch !. I may get a 40 dia knob and have it turned down to correct dia. Thanks for your help.

 

Can someone measure the distance across the guide shaft please - outer edge of left hand ball knob to outer edge of right hand ball knob ……. Thanks

 

Anyone help. It's only a quick measure with a vernier or a straight edge and tape measure. I will be fitting new ball ends so i need the overall distance to ensure they will fit the panniers etc. Thanks .... m

 

Good idea. Will try if no answers.
