RE: no K9 plugs on 2006 Pure Acids
The boards are shipped from the factory to importer/distributor
basically in order of production, which = order of serial numbers.
It's a pity that you have missed out on K9's if you really wanted them.
My 06 PA80 also missed out, totally fine and no problem without them.
In fact a lot of guys are not using them even when shipped, inc me !!)
Make sure you get the strap exchange/upgrade though.
That one really does count...
