On the rear of my 2006 2500 manual transmission where the cross member goes across and the transmission is bolted to the rubber mount I have broken my studs and drilled and put in titanium extra large bolts. Small titanium's break to easy. But where the studs mount to the rubber mount the rubber seams to loose I can move the tranny a little more than I want to.... Is there any transmission mount upgrades out there. Polyurethane ones would be nice Thanks...
