Re: steering column length? CJ.
On my '78 there's 5 1/2" from the firewall to the end of the spline. There's 10 1/4" from the dash to the end of the the steering column. Then about 3/16" gap to the base of the steering wheel hub. The steering shaft is about 29" from U-joint center to center.
As you are doing, I used the stock steering shaft so that it would collapse in a crash, but also incorporated a U-joint slip yoke to handle minor changes in the firewall-to-steering box distance. That changes about 3/16" as the body and frame flex, and I expect will change more as the body mounts sag.
