Steering shaft cover? Worm gear?

Ok guys, I give up. I am having all kinds of steering issues with my 70 dart. There is SO much slop in the steering its almost scary. I heard a rumor that, CAREFULLY adjusting the worm gear would help with the slop. The entire front end has been redone with polyurethane bushing and new steering components. I really do not want to buy a new gear considering that all the aftermarket ones i know of are junk.


Also, this cover pictured below. WHAT IS THE TRICK TO GETTING IT BACK ON WITHOUT PULLING MY MOTOR AND STEERING GEAR OUT?
