Title: Tank Badge Treads
Post by: Howard on 28.06. 2011 22:44
My 51 A7 petrol tank has had the bolt holes for the badges and knee pads, filled with what looks like body filler. I want to try and drill this out and run a tread tap down the holes. Does anyone know what tread these would be ? Thanks, regards Howard

Howard,
                  Knee pads screws should be 1/4"x 26 TPI.
