Kickstart Shaft Spring Placement

[AndyVee]

Need to replace an old shaft due to spline wear and sourced a replacement but noticed that the hole for the spring is in the wrong place (spring now rubs on housing).
Looking at the Sticky Bible it mentions different shaft lengths etc but nothing to do with hole placement. Is this a known problem or just a crap part I have sourced ?
3mm makes a real difference ! (not that my wife agrees). See pics :
