Roland,
I had to shorten my Lokar cable, and had a new set screw end to slide in place. I left it in the sheath, unhooked the pedal end for slack, extended the cable, taped it with masking tape, cut with a 4.5" angle grinder w/cutoff wheel and put the new end on (tape off now). Once the new end was on and tight I reinstalled the pedal end and hooked it up to the throttle body. Not sure it's the right way but it worked for me...
