So I found a 3D print firm that will make the plastic parts I need for my 63 Dynaflow. Anyone know the dimensions of the speedometer driven gear (the one that the speedometer cable attaches to)?
Its all different depending on your factory drive ratio's You would have to supply them a sample I hope they are cheap, this ones on ebay at about 10 bucks http://www.ebay.com/itm/NOS-GM-Spee...ash=item567f348901:g:j~0AAOSw8-tWYiDi&vxp=mtr Mick
