How rare are these and what trucks did they come in? Ive had SO many problems trying to get my FF to work I wish I wnt SF to begin with I got it all back to geather(except for i need a yoke) with the adapters and I HATE the look(they space the wheels a inch out) I look like a dually axle with single wheels. I dont have money for new wheels and tires So im gonna start looking for a 14bolt SF 6lug with disks and a posi (3.73)
