Quotethe ball ends just clip in place witha little force I liked your idea so ordered the same part from the USA. They arrived this evening so I thought I'd try popping one on just to see if they fit... How much force??? Did you use any lube or heat them in boiling wate or something first? They are the right size 6mm and I measured the balls at 6.0mm (+/- 0.1mm) too.by lord_alan - Fisher
