Barracuda tire Question

The wheel is stock steel cop car rim with no back space. I switched from drum to disc in the front. Will the rotor stick out more the old drum? I think it probably would. I did finally go under the car and check the torsion bar adjusting bolts. The driver side which is rubbing more than the passenger side adjusting bolt was loose. So much for the alignment shop. Top of tire to fender lip is 2"1/4 on driver side and 3" on passenger side. Not sure if that answers your question. Or do you want me to measure from center of rim to fender lip. Question does the tip of torsion bar adjusting bolt actually thread into that lever or just slide up inside. If its threaded I might have other issues.
