65 Barracuda Steering column cover length?

I am putting together my 65 Barracuda. I need to get the distance from the end of the steering column cover to the power steering pump fitting in order to re-attach my steering wheel. The steering wheel needs to slip onto the splines on the steering shaft at a certain depth in order for the trim section to butt up tightly underneath. I can pound the shaft further down towards the power steering box, but I don't want to go too far....Pushing the column back up into the car would be problematic due to the lack of space down there and the tight fit of the new column end trim parts . I hope this question makes sense. Thanks
