Formula Ford, Ray Haper for those of you here in the Midwest) and told him I wanted a Spitfire trans with a GT6 gear set. I told him that I understood it was necessary to shorten and re-spline the GT6 first motion shaft to get that done.<o:p></o:p></span></p>

had lying about. He gave me back a GT6 box with a Spitfire first motion shaft with an aluminum Spit bellhousing.<o:p></o:p></span></p>
