I would say the easiest way to tilt the column back, might be to use a U joint at the box, and then cut the column cover (and shaft) at the floor, this will kill 2 birds with one cut, both the angle and shorter problems that bother you... If needed to clear the U joint, you can use a cone shaped piece at the bottom of the column, then use a bigger floor mounting plate... Looks like the steering column is square with the frame now, but the whole car being on a rake, makes it look like it is tilting forward, no real biggy... and the length of the drag link is fine, if it were shorter, then it would also move more while going over bumps, if the front radius rods were longer, then the bump steer would be even less... IMHO
