ok guys, sorry for the delay but here is the steering shaft istall.
my steering column has been converted to 3/4" DD shaft on the end for quite some time now so there was no need for any machine work. I installed a flaming river steering universal joint from the column to a short chunk of stainless double D shaft. I then installed another universal joint from the steering rack to the double D shaft. the steering rack is 9/16x26 spline.
When ever your using DD steering shaft and universal joints it is critical to drill small indents into the steering shaft so that the set screws have a place to land.
IF YOU SKIP THIS STEP YOUR CAR WILL EXPLODE AND BE CONSUMED WITH FIRE.
