This is the first dd 9900 ever made they were custom built for Steve Cook a few years ago. they have standard slugs and a taller top plate. I have a re recone for this driver although the former seems a bit tight on the pole. I can include the recone with it, you can source parts for your own, or I can drop ship it to DD and they can recone it for you.
$165 shipped for the motor
$200 shipped with the 12" re recone
