The components were purchase from borgeson.com Starting from the rack and going towards the steering wheel....
I went with a polished stainless double u-joint 3/4"36 spline x DD at the steering rack, polished stainless 3/4" shaft, a 3/4" rod end for support of the shaft, then on to the polished stainless 3/4" DD x 3/4"36 spline single u-joint at the fire wall. I made a mounting plate at the fire wall to hold the carrier bearing which holds a 3/4" x 3.5" shaft with 36 splines on both ends, polished stainless 3/4" DD x 3/4" smooth bore single u-joint on the interior side of the fire wall, mating to a 3/4" solid round shaft that runs up toward the steering wheel thru the steering column. The top 9" of OEM steering shaft was pinned to the 3/4" shaft to allow the steering wheel to mount with factory splines and threads. There is a little trickery at the base of the steering column housing where I mounted another carrier bearing to support the shaft as it passed out of the column housing.
