So is there any reason to think that an E-locker from a new 2011 SuperDuty wouldn't fit in an older 10.25 Sterling? Taking for granted a hole would have to be drilled for the wires of course. Can anybody confirm if it takes a 12VDC signal to control it?
I belive that the only difference between the 10.5 and 10.25 rears in the ring and pinion and inner pinion bearing. I'm currently running '99 10.5 gears in my '97 10.25 with a 10.25 ls diff. So I don't see why you couldn't put your 10.25 gears on a 10.5 diff?
