OK…. The steering center bearing bracket and shaft assy can be lowered 1/8-1/4” into the front crossmember by removing the four bolts retaining it to the crossmember, and installing an equal number of flat washers at the four bolt locations (between the bearing bracket and bottom of crossmember)… then reinstall & tighten the four bolts.
Doing this in effect lowers the bell crank arm gaining additional crank pulley clearance on the Studes, and pulley & oil pan clearance on the Chevys ….It’s important though, to be careful not to lower the center bearing bracket to the point where the bell crank arm interferes (or rubs) the front crossmember!
