Hell i aint worried about the trunions at all, mine already need replacing so im just gettin the eliminator kit. I mean if i was gonna do it all again, i would of just gone full width in the first place but my toy axles are geared, locked, with chomoly shafts and hub gears. it would be stupid to start all over again. Soo wheel spacers and backspacing are what i need, that an some extra weight from an ifs rear, trussing, skid plate, duals, etc. all that down low gear.
